Description

Technical Field

[0001] This utility model relates to the technical field of golf bag trolleys, and in particular to a folding structure for a golf bag trolley. Background Technology

[0002] A golf bag trolley is a device used in golf to carry and transport golf bags. It consists of a lower frame, an upper frame, and handlebars. The lower frame has wheels attached to its bottom; the upper frame is connected to the lower frame and extends upwards to hold the golf bags. The handlebars are attached to the upper frame for user operation. Traditional golf bag trolleys are relatively large, taking up a lot of space when not in use, making them inconvenient to store and move.

[0003] In related technologies, some golf bag trolleys are designed to be foldable for easy storage. For example, in some designs, the upper frame of the golf bag trolley is connected to the lower frame via a telescopic rod, and the height of the upper frame is adjusted by extending or retracting the rod. In this design, because the telescopic rod still occupies a certain amount of height, the space occupied by the upper frame when retracted is still relatively large. In some designs, the upper frame is hinged to the lower frame and locked with pins when the upper frame is unfolded or folded relative to the lower frame. This folding design requires the operator to bend over to insert and remove the pins, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a folding structure for a golf bag trolley, which can easily fold and unfold the golf bag trolley, making it space-saving and easy to store and transport when not in use.

The linkage assembly passes through the upper frame tube, and its two ends are respectively connected to the folding lever and the locking element.

[0007] The elastic element provides a force to the locking element in the direction of the rotating groove; the sidewall of the rotating groove is provided with a first locking groove and a second locking groove on the side of the first sliding groove; when the upper frame tube is in the unfolded state, the locking element is locked in the first locking groove; when the upper frame tube is in the folded state, the locking element is locked in the second locking groove; the retracting lever can move relative to the upper frame tube to pull the locking element away from the first locking groove or the second locking groove.

[0008] Furthermore, the linkage component includes a steel wire, one end of which is connected to the locking member, and the other end of which is connected to the retraction lever.

[0009] Furthermore, the linkage assembly also includes an upper slider and a lower slider. The upper slider is slidably fitted inside the upper frame tube and connected to the retraction lever. The lower slider is slidably disposed inside the upper frame tube and connected to the locking member. The two ends of the steel wire are respectively connected to the upper slider and the lower slider.

[0010] Furthermore, the elastic element includes a compression spring. A tube plug is provided inside one end of the upper frame tube facing the rotating groove. A spring cavity with an opening facing the rotating groove is formed inside the tube plug. The compression spring is disposed in the spring cavity and abuts against the bottom wall of the spring cavity. The lower slider is slidably fitted into the spring cavity and abuts against the compression spring. The steel wire passes through the tube plug and is connected to the lower slider.

[0011] Furthermore, the lower slider has a first mounting hole, the side wall of the tube plug has a relief groove aligned with the first sliding groove, the locking member is fitted into the first mounting hole, and at least part of the locking member passes through the first mounting hole and exits from the relief groove and the first sliding groove.

[0012] Furthermore, a second sliding groove is provided along the length direction at one end of the upper frame tube away from the rotating groove, and the retracting lever is provided with a connecting hole aligned with the second sliding groove. A connecting shaft is slidably inserted in the second sliding groove. The connecting shaft passes through both the second sliding groove and the connecting hole and is axially limited to the retracting lever. The upper slider is connected to the connecting shaft.

[0013] Furthermore, the upper frame assembly also includes an upper support seat, which is connected to the end of the upper frame tube away from the rotating groove. The upper support seat is provided with a third sliding groove aligned with the second sliding groove. The retraction lever is disposed outside the third sliding groove, and the connecting shaft passes through the third sliding groove and is connected to the retraction lever. The retraction lever is rotatably connected to the upper support seat, and the connecting hole is an elongated hole through which the connecting shaft can slide.

[0014] Furthermore, the two ends of the steel wire are connected to limit blocks, and both the upper slider and the lower slider are provided with limit holes, with the limit blocks fitting into the limit holes; both the upper slider and the lower slider are provided with clearance joints, which are connected to the limit holes, and the steel wire passes through the clearance joints.

[0015] Furthermore, the upper frame assembly also includes a sleeve, which is fitted onto one end of the upper frame tube facing the rotating groove; the sleeve is provided with a fourth sliding groove aligned with the first sliding groove, and the locking member extends out of the fourth sliding groove and can slide along the fourth sliding groove.

[0016] Furthermore, the side wall of the rotating groove is also provided with an arc-shaped sliding groove, the center of which coincides with the rotation connection point of the upper frame tube and the rotating groove, and the two ends of the arc-shaped sliding groove are respectively connected to the first locking groove and the second locking groove.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. In the folding structure of the golf bag trolley of this utility model, the upper frame assembly is connected above the lower frame assembly. The upper frame tube of the upper frame assembly is rotatably connected to the rotating groove of the lower frame assembly. The rotating groove is provided with a first locking groove and a second locking groove. When the golf bag trolley needs to be used, the upper frame tube rotates to the unfolded state. At this time, the locking member moves along the first sliding groove under the action of the elastic member and inserts into the first locking groove, thereby locking the upper frame tube. The upper frame tube cannot rotate relative to the rotating groove. At this time, the upper frame tube remains upright on the lower frame assembly so that the operator can push the golf bag trolley. When the golf bag trolley needs to be folded, the operator pulls the folding lever upwards. The folding lever pulls the locking member through the linkage component, causing the locking member to disengage from the first locking groove. The upper frame tube is then rotated towards the lower frame assembly to fold it until the locking member aligns with the second locking groove. At this point, the folding lever is released, and the locking member is inserted into the second locking groove under the action of the elastic member, thus locking the upper frame tube.

[0019] Therefore, the folding structure of this utility model does not require the operator to bend over to insert or remove pins. The operator only needs to lift the folding lever and rotate the upper frame tube. The operation is simple and convenient. Moreover, the overall space occupied by the folding structure is reduced after the upper frame tube is folded, which makes it convenient for storing and transporting golf bag trolleys.

[0020] 2. In this invention, the linkage component includes a steel wire, which connects the retraction lever and the locking component, enabling the retraction lever to pull the locking component. This configuration also makes the linkage component smaller in size and weight, facilitating its installation, reducing the weight of the retraction structure, and making it easier for the user to operate.

[0021] 3. The upper and lower sliders are connected to the two ends of the steel wire respectively. The upper and lower sliders are connected to the retraction lever and the locking component respectively. The upper and lower sliders can be slidably set inside the upper frame tube, which facilitates the connection between the steel wire and the retraction lever and the locking component. At the same time, it makes the retraction lever and the elastic component pull linkage assembly move more stably and smoothly inside the upper frame tube. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] This embodiment discloses a folding structure 1000 for a golf bag trolley, referring to... Figure 1 and Figure 2 The cart retrieval structure 1000 includes an upper frame assembly 200 and a lower frame assembly 100, with the upper frame assembly 200 connected above the lower frame assembly 100. The front wheels 2000 and rear wheels 3000 of the golf bag cart are connected to the lower part of the lower frame assembly 100, and the end of the upper frame assembly 200 away from the lower frame assembly 100 is connected to the handlebar 4000 of the golf bag cart. The upper frame assembly 200 and the lower frame assembly 100 are used to carry golf bags.

[0034] Reference Figure 3 and Figure 4 The lower frame assembly 100 includes a base 110 and a connecting seat 120 connected as one piece. The base 110 has a front axle hole 111 for mounting the front wheel 2000 at its front end, and a rear axle hole 112 for mounting the rear wheel 3000 at its rear end. A support groove 113 for supporting the bottom of a golf bag is provided on the top of the base 110. The connecting seat 120 is located above the base 110 and has a rotating groove 121 that extends through the upper and front sides of the connecting seat 120, forming openings on both sides. The upper frame assembly 200 is inserted into the rotating groove 121 and rotatably connected to the inner wall of the rotating groove 121.

[0035] Reference Figures 4 to 7 The upper frame assembly 200 includes an upper support 210, an upper frame tube 220, a take-off lever 230, a linkage assembly 240, a locking element 250, and an elastic element 260. The upper support 210 is connected to the upper end of the upper frame tube 220 and supports the upper part of the golf bag. The lower end of the upper frame tube 220 (i.e., the end of the upper frame tube 220 near the connecting seat 120) is rotatably connected to a rotating groove 121. The take-off lever 230 is located at the end of the upper frame tube 220 away from the rotating groove 121 (i.e., the upper end of the upper frame tube 220) and is movable relative to the upper frame tube 220. The locking element 250 is movably located at the lower end of the upper frame tube 220. The linkage assembly 240 is located within the upper frame tube 220 and connects between the locking element 250 and the take-off lever 230. The elastic element 260 is disposed inside the upper frame tube 220 and is used to provide the locking element 250 with a force in the direction of the rotating groove 121.

[0036] Reference Figure 4 and Figure 6 In this embodiment, a first rotating hole 221 is provided at the lower end of the upper frame tube 220, and a second rotating hole 122 is provided on the inner wall of the rotating groove 121. The first rotating hole 221 and the second rotating hole 122 are aligned, and a rotating pin 300 is inserted into both the first rotating hole 221 and the second rotating hole 122. Both ends of the rotating pin 300 protrude from the second rotating hole 122 and protrude from the opposite sides of the connecting seat 120 and are provided with external threads. The threaded portion of the rotating pin 300 protruding from the connecting seat 120 is fitted with a locking nut. In this way, the upper frame tube 220 is rotatably connected to the rotating groove 121.

[0037] In other embodiments, the upper frame tube 220 and the rotating groove 121 can also be rotatably connected in other suitable ways. For example, the rotating pin 300 can be fixed in one of the upper frame tube 220 and the rotating groove 121, and a hole that mates with the rotating pin 300 can be provided on the other of the upper frame tube 220 and the rotating groove 121. Alternatively, the inner walls of the upper frame tube 220 and the rotating groove 121 can also be connected by a hinge.

[0038] Reference Figure 3 and Figure 4The sidewall of the rotating groove 121 is provided with a first locking groove 123 and a second locking groove 124. The first locking groove 123 and the second locking groove 124 extend radially along the second rotating hole 122. The first locking groove 123 is positioned above the lower frame assembly 100, and the second locking groove 124 is positioned in front of the lower frame assembly 100. Here, "above" and "front" are based on the usage of the golf bag trolley. "Above" is the direction away from the ground, and "front" is the direction of the golf bag trolley from the rear wheel 3000 to the front wheel 2000. The locking member 250 is adapted to the first locking groove 123 and the second locking groove 124, that is, the locking member 250 can be inserted into the first locking groove 123 or the second locking groove 124 to lock the upper frame tube 220 in the rotating groove 121, so that the upper frame tube 220 cannot rotate relative to the rotating groove 121.

[0039] When the golf bag trolley needs to be used, the top rack tube 220 is rotated to the position as follows: Figure 3 In the unfolded state shown, the upper frame tube 220 is rotated to face upwards. At this time, the locking member 250 is inserted into the first locking groove 123 under the action of the elastic member 260, thereby locking the upper frame tube 220. The upper frame tube 220 cannot rotate relative to the rotating groove 121. The upper frame tube 220 remains upright on the lower frame assembly 100 so that the operator can push the golf bag trolley.

[0040] like Figure 8 As shown, when the golf bag trolley needs to be folded, the operator pulls the folding lever 230 upwards. The folding lever 230 pulls the locking member 250 through the linkage component 240, causing the locking member 250 to disengage from the first locking groove 123. At this time, the upper frame tube 220 is rotated towards the lower frame assembly 100 to fold it until the locking member 250 is aligned with the second locking groove 124. Then, the folding lever 230 is released, and the locking member 250 is inserted into the second locking groove 124 under the action of the elastic member 260, thus locking the upper frame tube 220. Therefore, the operator does not need to bend over to insert or remove pins; simply pulling the folding lever 230 and rotating the upper frame tube 220 is sufficient to fold the golf bag trolley. The operation is simple and convenient, and the overall space occupied by the folding structure 1000 is reduced after the upper frame tube 220 is folded, making it easier to store and transport the golf bag trolley.

[0041] Reference Figure 4 and Figure 6The upper frame tube 220 has a first sliding groove 222 at one end near the rotating groove 121. The first sliding groove 222 is an elongated groove and extends along the length of the upper frame tube 220. The locking member 250 is vertically inserted into the upper frame tube 220 from the first sliding groove 222. The end of the locking member 250 extends out of the first sliding groove 222 to insert into the first locking groove 123 or the second locking groove 124. The locking member 250 can slide along the length of the first sliding groove 222 to insert into / disengage from the first locking groove 123 or the second locking groove 124.

[0042] In this embodiment, the first sliding groove 222 is provided on both opposite sides of the upper frame tube 220, and the two first sliding grooves 222 are arranged opposite to each other. The two ends of the locking member 250 extend out of the upper frame tube 220 from the two first sliding grooves 222. Correspondingly, the opposite sides of the rotating groove 121 are provided with a first locking groove 123 and a second locking groove 124, and the two first locking grooves 123 and the two second locking grooves 124 are arranged opposite to each other. Thus, the two ends of the locking member 250 are respectively inserted into the first locking groove 123 or the second locking groove 124 on both sides, making the connection between the upper frame assembly 200 and the lower frame assembly 100 more stable and reliable. In addition, in other embodiments, the first sliding groove 222 may be provided only on one side of the upper frame tube 220, and the first locking groove 123 and the second locking groove 124 may be provided only on one side of the inner wall of the rotating groove 121.

[0043] Reference Figure 3 and Figure 4 The side wall of the rotating groove 121 is also provided with an arc-shaped sliding groove 125, which is concentrically arranged with the second rotating hole 122. The first end of the arc-shaped sliding groove 125 is connected to the end of the first locking groove 123 away from the second rotating hole 122, and the second end of the arc-shaped sliding groove 125 is connected to the end of the second locking groove 124 away from the second rotating hole 122. Thus, after the locking member 250 disengages from the first locking groove 123 or the second locking groove 124, the locking member 250 enters the arc-shaped sliding groove 125. When the upper frame tube 220 is rotated to fold or unfold the golf bag trolley, the locking member 250 slides along the arc-shaped sliding groove 125, making the sliding of the locking member 250 stable and smooth, and at the same time facilitating the positioning and sliding of the locking member 250 to the opening of the first locking groove 123 or the second locking groove 124.

[0044] In addition, in other embodiments, the arc-shaped groove 125 may be omitted, and the first locking groove 123 and the second locking groove 124 may directly pass through the connecting seat 120 to form an opening for the locking member 250 to be inserted.

[0045] In this embodiment, the first locking groove 123, the second locking groove 124, and the arc-shaped sliding groove 125 all penetrate the side wall of the connecting seat 120, such that one side opening of the first locking groove 123, the second locking groove 124, and the arc-shaped sliding groove 125 communicates with the rotating groove 121, and the other side opening communicates with the outside. Furthermore, in other embodiments, the first locking groove 123, the second locking groove 124, and the arc-shaped sliding groove 125 may not penetrate the connecting seat 120.

[0046] Reference Figure 6 In this embodiment, the locking member 250 is a cylindrical pin to reduce the probability of stress concentration damage to the periphery of the locking member 250 when it slides in the first locking groove 123, the second locking groove 124, and the sliding groove. In other embodiments, the locking member 250 may also be a prism, frustum, cone, or other regular or irregular shape.

[0047] Reference Figures 4 to 7 In this embodiment, a sleeve 270 is provided on the side of the upper frame tube 220 facing the rotating groove 121. The sleeve 270 is fitted over the end of the upper frame tube 220 facing the rotating groove 121, and the lower end of the upper frame tube 220 is blocked by the sleeve 270 to prevent external debris from entering the upper frame tube 220, and at the same time to make it difficult for parts inside the upper frame tube 220 to fall out from the opening at the lower end of the upper frame tube 220.

[0048] Reference Figures 4 to 6 The sleeve 270 is provided with a fourth slide groove 271 aligned with the first slide groove 222, and a third rotation hole 272 aligned with the first rotation hole 221. The fourth slide groove 271 is an elongated groove extending along the length of the upper frame tube 220, allowing it to completely align and overlap with the first slide groove 222. This allows the locking member 250 to pass through both the first and fourth slide grooves 222 and slide along the first and fourth slide grooves 271. The rotating pin 300 passes through the first and third rotation holes 221 and then engages with the second rotation hole 122, preventing the sleeve 270 from covering the first rotation hole 221 and simultaneously connecting the sleeve 270 and the upper frame tube 220.

[0049] In addition, in other embodiments, the position and length of the sleeve 270 can be changed so that the sleeve 270 does not cover the first rotating hole 221 and the first sliding groove 222, thereby eliminating the need to provide a third rotating hole 272 and a fourth sliding groove 271 on the sleeve 270.

[0050] The outer circumferential surface of the end of the sleeve 270 away from the upper frame tube 220 is round, which makes the sleeve 270 rotate more smoothly and stably with the upper frame tube 220. In addition, in other embodiments, the sleeve 270 may also be other suitable shapes.

[0051] In addition, in other embodiments, the sleeve 270 may not be provided.

[0052] Reference Figure 6 and Figure 7 In this embodiment, the linkage component 240 includes a steel wire 241, an upper slider 242, and a lower slider 243. The upper slider 242 is slidably fitted inside the upper end of the upper frame tube 220 and connected to the retraction lever 230. The lower slider 243 is slidably disposed inside the lower end of the upper frame tube 220 and connected to the locking member 250. The two ends of the steel wire 241 are respectively connected to the upper slider 242 and the lower slider 243, so that one end of the steel wire 241 is connected to the locking member 250, and the end of the steel wire 241 away from the locking member 250 is connected to the retraction lever 230. Therefore, when the operator moves the retraction lever 230 away from the rotating groove 121, the retraction lever 230 drives the upper slider 242 to move, thereby pulling the lower slider 243 and the locking member 250 away from the rotating groove 121 through the steel wire 241, overcoming the elastic force of the elastic member 260. This causes the locking member 250 to disengage from the first locking groove 123 or the second locking groove 124. When the operator releases the retraction lever 230, the elastic member 260 pulls the locking member 250 towards the rotating groove 121, causing the locking member 250 to insert into the first locking groove 123 or the second locking groove 124. At the same time, the locking member 250 pulls the retraction lever 230 back to its original position through the lower slider 243, the steel wire 241, and the upper slider 242.

[0053] Furthermore, in other embodiments, the linkage component 240 may also take other forms, as long as it can transmit the tension between the locking member 250 and the retraction lever 230. For example, in one embodiment, the linkage component 240 may consist of only a steel wire 241, which is directly connected to the retraction lever 230 and the locking member 250. In one embodiment, the linkage component 240 may also be a thin rod, with both ends connected to the retraction lever 230 and the locking member 250, respectively.

[0054] In this embodiment, the two ends of the steel wire 241 are connected to limit blocks 244. Both the upper slider 242 and the lower slider 243 are provided with limit holes 245, and the limit blocks 244 fit into the limit holes 245. Both the upper slider 242 and the lower slider 243 are provided with clearance slots 246, which connect to the limit holes 245. The width of the clearance slots 246 is smaller than the width of the limit blocks 244, allowing the steel wire 241 to pass through the clearance slots 246, while the limit holes 245 are confined within them. This facilitates the connection of the steel wire 241 to the upper slider 242 and the lower slider 243.

[0055] Reference Figure 6 and Figure 7In this embodiment, the elastic element 260 includes a compression spring, which abuts against the end of the lower slider 243 facing away from the rotating groove 121. Specifically, a tube plug 280 is fixedly disposed inside the end of the upper frame tube 220 facing the rotating groove 121. A spring cavity 281 with an opening facing the rotating groove 121 is formed inside the tube plug 280. The compression spring is disposed inside the spring cavity 281 and abuts against the bottom wall of the spring cavity 281. The lower slider 243 is slidably fitted inside the spring cavity 281, and the lower slider 243 fits into the spring cavity 281. The end of the lower slider 243 facing the steel wire 241 abuts against the compression spring. The bottom wall of the tube plug 280 is provided with an opening facing the upper slider 242. The steel wire 241 passes through the opening of the bottom wall of the tube plug 280 and the inner cavity of the compression spring and connects to the lower slider 243.

[0056] Therefore, when the operator pulls the retraction lever 230, causing the lower slider 243 to move away from the rotating groove 121, the lower slider 243 and the pipe plug 280 compress the spring, and the elastic element 260 accumulates elastic force. When the operator releases the retraction lever 230, the spring releases its elastic force, driving the lower slider 243 to move towards the rotating groove 121.

[0057] Furthermore, in other embodiments, the elastic element 260 may take other forms. For example, in one embodiment, the elastic element 260 may be a tension spring or elastic cord, connected to the end of the lower slider 243 facing the rotating groove 121. In one embodiment, the elastic element 260 may also be a torsion spring, coil spring, or other suitable spring.

[0058] In this embodiment, the sliding block 243 has a first mounting hole 247, which penetrates the sliding block 243 and aligns with the first sliding groove 222. The side wall of the plug 280 has a clearance groove 282 aligned with the first sliding groove 222. The locking member 250 is inserted into the first mounting hole 247, and at least a portion of the locking member 250 passes through the first mounting hole 247 and exits through the clearance groove 282 and the first sliding groove 222. The clearance groove 282 is an elongated groove that completely overlaps with the first sliding groove 222, thus ensuring that the plug 280 does not interfere with the locking member 250, guaranteeing that the locking member 250 can slide normally within the first sliding groove 222.

[0059] The tube plug 280 is also provided with a fourth rotating hole 283 that aligns with the first rotating hole 221, so that the rotating pin 300 can pass through the first rotating hole 221, the third rotating hole 272 and the fourth rotating hole 283 at the same time, connecting the upper frame tube 220, the tube plug 280 and the tube sleeve 270 into a whole, making the overall stability of the upper frame assembly 200 better and the structure more reasonable.

[0060] Reference Figure 6 and Figure 7In this embodiment, a second sliding groove 223 is provided along the length of the end of the upper frame tube 220 away from the rotating groove 121, and the retraction lever 230 is provided with a connecting hole 231 aligned with the second sliding groove 223. In this embodiment, the second sliding groove 223 is provided on both opposite sides of the upper frame tube 220, and the retraction lever 230 is C-shaped and semi-encloses the upper frame tube 220. The retraction lever 230 is provided with connecting holes 231 on both arms of the second sliding groove 223 on both sides of the upper frame tube 220.

[0061] A connecting shaft 400 is slidably inserted into the second slide groove 223. The connecting shaft 400 passes through the upper frame tube 220, and both ends of the connecting shaft 400 exit from two opposing second slide grooves 223 and pass through two connecting holes 231. In this embodiment, the connecting shaft 400 is specifically a connecting bolt. The head of the connecting bolt is limited to one of the two connecting holes 231, and the tail of the connecting bolt passes through the other connecting hole 231 and is threaded into a connecting nut, thereby limiting the connecting bolt relative to the retraction lever 230 along its axial direction.

[0062] In this embodiment, the upper slider 242 is provided with a second mounting hole 248, which is aligned with the second slide groove 223 and the connecting hole 231. The connecting bolt passes through the second mounting hole 248, thereby connecting the upper slider 242 to the retraction lever 230. Pulling the retraction lever 230 in a direction away from the rotating groove 121 will move the upper slider 242, steel wire 241, lower slider 243, and locking member 250 in a direction away from the rotating groove 121. In other embodiments, the upper slider 242 may also be connected to the retraction lever 230 in other suitable ways.

[0063] Reference Figures 5 to 7 In this embodiment, the upper support 210 is connected to the end of the upper frame tube 220 away from the rotating groove 121. A C-shaped support frame 211 is formed on the front side of the upper support 210, and the upper part of the golf bag is clamped and supported by the C-shaped support frame 211.

[0064] The upper bearing 210 extends beyond the second slide groove 223. The upper bearing 210 is provided with a third slide groove 212 aligned with the second slide groove 223. The third slide groove 212 is an elongated groove overlapping the second slide groove 223. A retraction lever 230 is disposed outside the third slide groove 212, and a connecting shaft 400 passes through the third slide groove 212 and connects to the retraction lever 230. Alternatively, in other embodiments, a certain distance may be left between the upper bearing 210 and the second slide groove 223, thus eliminating the need for a third slide groove 212 on the upper bearing 210.

[0065] In this embodiment, the retraction lever 230 is rotatably connected to the upper support 210. Specifically, the C-shaped retraction lever 230 includes two arms 232 and an intermediate connecting portion 233 connecting the two arms 232. The outer ends of the two arms 232 (i.e., the ends of the two arms 232 of the retraction lever 230 away from the intermediate connecting portion 233) are provided with a first pivot hole 234, and the upper support 210 is provided with a second pivot hole 213. The first pivot hole 234 and the second pivot hole 213 are aligned and a pivot shaft 500 is passed through them simultaneously to realize the rotatable connection between the retraction lever 230 and the upper support 210.

[0066] In this embodiment, the pivot shaft 500 is specifically a pivot bolt, the head of which is confined to the outside of a first pivot hole 234, and the tail of which passes through another first pivot hole 234 and is threaded into a nut. In other embodiments, the pivot shaft 500 may also be a pin or other suitable shaft-like component.

[0067] In this embodiment, the connecting hole 231 is located between the first pivot hole and the intermediate connecting portion 233 on the retraction lever 230. The connecting hole 231 is an elongated hole, and its length direction is not parallel to the length direction of the second slide groove 223. The connecting shaft 400 can slide through the connecting hole 231 along its length direction. Thus, the operator can pull the intermediate connecting portion 233 upwards, causing the retraction lever 230 to rotate around the pivot shaft 500, thereby moving the connecting shaft 400 and the upper slider 242 away from the rotating groove 121 with less effort.

[0068] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
