[0030] Example 1

[0031] Reference Figures 1-3 This is the first embodiment of the present utility model. This embodiment provides a telescopic mechanism, which includes a telescopic unit 100 comprising a rotating component 101, a pop-out component 102 disposed below the rotating component 101, and a protective component 103 disposed outside the pop-out component 102.

[0032] The clamping unit 200 includes a fixed wrench 201 and a movable wrench 202 disposed on one side of the fixed wrench 201;

[0033] The telescopic unit 100 is located in the inner cavity of one end of the fixed wrench 201.

[0034] It should be noted that the rotating component 101 is located above the pop-out component 102 and is concentric and vertical, and the protective component 103 is wrapped around the outside of the pop-out component 103. The fixed wrench 201 has a rectangular groove, through which the movable wrench 202 passes. The teeth of the fixed wrench 201 and the teeth of the movable wrench 202 are engaged. The telescopic unit 100 is disposed in the inner cavity of the movable wrench 202, with one end inside the inner cavity and the other end extending out of the inner cavity of the movable wrench 202.

[0035] In use, the rotating component 101 is located above the pop-out component 102. By rotating the rotating component 101, the pop-out component 102 is popped out. It can pop out or retract depending on the usage. When the wrench clamps the ring, the telescopic unit 100 cooperates to clamp the ring during the clamping process.

[0036] In summary, when clamping a ring, the clamping unit 200, through the cooperation of the fixed wrench 201 and the movable wrench 202, firstly achieves stable clamping of the target object. By rotating the rotating component 101, the pop-out component 102 can be popped out or retracted to a suitable position as needed. During the clamping process, the telescopic unit 100 and the clamping unit 200 work closely together to ensure the stability and accuracy of the clamping, solving the problem of the wrench slipping when clamping a ring.

[0037] Example 2

[0038] Reference Figures 1-3 This is the second embodiment of the present utility model, which differs from the first embodiment in that it also includes a telescopic unit 100 including a rotating component 101, a pop-out component 102 disposed below the rotating component 101, and a protective component 103 disposed outside the pop-out component 102.

[0039] The clamping unit 200 includes a fixed wrench 201 and a movable wrench 202 disposed on one side of the fixed wrench 201;

[0040] The telescopic unit 100 is located in the inner cavity of one end of the fixed wrench 201.

[0041] It should be noted that the rotating component 101 is located directly above the ejector component 102, and the two are concentric and vertically arranged. The protective component 103 is wrapped around the outside of the ejector component 102. A rectangular groove is opened in the center of the fixed wrench 201, through which the adjustable wrench 202 passes and intersects with the fixed wrench 201. The teeth of the fixed wrench 201 and the teeth of the adjustable wrench 202 match each other, ensuring a stable fit between the two during operation.

[0042] Furthermore, the adjustable wrench 202 includes a first flat tooth 202a disposed at its front end, a trapezoidal tooth 202b disposed on one side of the first flat tooth 202a, and a second flat tooth 202c disposed at the front end of the trapezoidal tooth 202b.

[0043] The fixed wrench 201 and the adjustable wrench 202 have the same tooth shape.

[0044] It should be noted that the first flat tooth 202a is located close to the adjustable wrench 202, the second flat tooth is located at the end of the adjustable wrench 202c, and the trapezoidal tooth 202b is located between the first flat tooth 202a and the second flat tooth 202c. When clamping an object, it is mainly clamped by the first flat tooth 202a of the adjustable wrench 202 and the flat tooth of the fixed wrench 201. The fixed wrench 201 and the adjustable wrench 202 have the same tooth shape, mainly for the purpose of facilitating mutual cooperation.

[0045] Furthermore, the rotating assembly 101 includes a rotating head 101a, a rotating component 101b disposed below the rotating head 101a, and a circular groove 101c formed in the rotating head 101a.

[0046] It should be noted that the bottom of the rotating head 101a has a protruding locking piece that matches the groove on the upper surface of the rotating part 101b. The rotating head 101a is cylindrical, and a circular groove 101c is provided on its side along the axis.

[0047] Furthermore, the pop-out component 102 includes a telescopic rod 102a disposed below the rotating member 101b, and a spring 102b disposed around the telescopic rod 102a.

[0048] It should be noted that the lower protrusion of the rotating component 101b cooperates with the upper groove of the telescopic rod 102a. The rotating component 101b causes the lower protrusion to rotate along the groove on the upper part of the telescopic rod 102a to a designated position, so that the telescopic rod 102a can extend and retract. A spring 102b is provided on the periphery of the telescopic rod 102a, which can retract the spring 102b more quickly.

[0049] Furthermore, the protective assembly 103 includes a knob 103a disposed around the rotator 101b, and a housing 103b disposed below the knob 103a.

[0050] It should be noted that a recessed thread is provided at the bottom of the inner cavity of the rotating part 103, and a raised thread is provided on the outer side of the upper part of the housing 103b, so that the rotating part 103 and the housing 103b can be connected by rotation.

[0051] Furthermore, the rotating head 101a, the rotating component 101b, and the telescopic rod 102a are all aligned on the same axis.

[0052] It should be noted that the bottom of the rotating head 101a is connected to the top of the rotating component 101b, and the bottom of the rotating component 101b is matched with the top of the telescopic rod 102a. The three are in a vertical connection relationship.

[0053] In use, the fixed wrench 201 and the adjustable wrench 202 work together to clamp the ring. During clamping, the rotating head 101a in the telescopic unit 100 rotates, causing the rotating part 101b to rotate. This causes the bottom of the rotating part 101b to rotate, engaging with the top part of the telescopic rod 102a, so that one end of the telescopic rod 102a extends from the teeth of the fixed wrench 201 to the surface of the teeth of the adjustable wrench 202 and stops. While the two wrenches are clamping the ring, they simultaneously rotate the rotating head 101a, extending the telescopic rod 102a. When it is necessary to release the ring, the adjustable wrench 202 is rotated away from the fixed wrench 201. The rotating head 101a in the telescopic unit 100 rotates in the opposite direction, causing the telescopic rod 102a to retract back into the housing 103b.

[0054] In summary, the coordinated action of the rotating assembly 101 and the ejector assembly 102 enables the clamping and rapid release of workpieces such as rings. The cooperation between the rotating head 101a and the rotating component 101b, and the rapid extension and retraction of the telescopic rod 102a with the assistance of the spring 102b, ensure efficient and accurate operation. The cross-connection of the fixed wrench 201 and the movable wrench 202, along with the tight fit of the teeth, provides the wrench with powerful clamping force. The telescopic rod 102a extending from the telescopic unit 100 effectively solves the problems of the wrench slipping and the ring rotating during the clamping and rotation process.

[0055] Example 3

[0056] Reference Figures 1-4 This is the third embodiment of the present invention, which further provides a telescopic mechanism and a wrench device. It includes a rotating unit 300, a fixing component 301, and a locking component 302 disposed on one side of the fixing component 301.

[0057] Furthermore, the fixing component 301 includes a rotating shaft 301a and a fixing block 301b disposed on the inner wall of one side of the adjustable wrench 202.

[0058] Furthermore, the locking assembly 302 includes a ratchet 302a disposed on the inner wall of one side of the fixed wrench 201, a pawl 302b disposed on one side of the movable wrench 202, and an annular groove 302c formed on one side of the ratchet 302a.

[0059] Furthermore, it also includes a drive rope 400 disposed in the fixed wrench 201;

[0060] Furthermore, one end of the drive rope 400 is tied to the circular groove 101c, and the other end is tied to the annular groove 302c.

[0061] It should be noted that the rotating shaft 301a passes through the groove between the fixed wrench 201 and the movable wrench 202, the fixed block 301b is installed on one side of the movable wrench 202, and the pawl 302b is fixedly connected to the fixed block 301b. The ratchet 302a is set on the inner wall of the fixed wrench 201 and is coaxial with the rotating shaft 301a. The annular groove 302c is set on one side of the ratchet 302a. One end of the drive rope 400 is fixed in the annular groove 302c and the other end is fixed in the circular groove 101c.

[0062] In use, when the ring is clamped by the fixed wrench 201 and the movable wrench 202, the rotation of the fixed wrench 201 drives the ratchet 302a to rotate, causing the drive rope 400 in the annular groove 302c to rotate. The drive rope 400 then pulls the drive rope in the circular groove 101c, causing the rotating head 101a to rotate and control the telescopic unit. Once the ring is clamped, rotating the fixed wrench 201 directly engages the ratchet 302a, which is then locked by the pawl 302b, ensuring a secure clamping of the ring.

[0063] In summary, the rotating unit 300, through the cooperation of the fixing component 301 and the locking component 302, achieves a stable connection and locking function between the fixed wrench 201 and the movable wrench 202, ensuring that the wrench is not easily dislodged when rotating the ring. When the fixed wrench 201 rotates, the ratchet 302a can drive the drive rope 400 in the annular groove 302c to rotate, thereby realizing remote control of the telescopic unit 100, further improving the practicality of the tool, and solving the problem of being able to make the telescopic rod pop out when the wrench is rotated without the need for manual control of the telescopic unit 100.
