Technical Field

[0001] This utility model belongs to the field of tools, specifically relating to a universal sleeve. Background Technology

[0002] During the screw tightening process in photovoltaic power generation engineering construction, a special tool with a universal socket head, connecting rod, and an electric wrench on the other side is usually used to tighten the screws inside the C-shaped purlins of the photovoltaic system. This solves the problem that the screws inside the C-shaped purlins of the photovoltaic support system in the photovoltaic area are difficult to tighten.

[0003] However, in actual use, due to the narrow space inside the C-shaped purlin and the inclined direction of the sleeve, the sleeve is prone to loosening from the screw, affecting its use. To solve the above problems, a universal sleeve is proposed. Utility Model Content

[0004] In view of one or more of the above-mentioned defects or improvement needs of the prior art, the present invention provides a universal sleeve with the advantage of high stability.

[0005] To achieve the above objectives, this utility model provides a universal sleeve, including an extension rod;

[0006] The connector is detachably mounted at one end of the extension rod;

[0007] The universal joint is located at the other end of the extension rod, and the outer wall of the universal joint has a prismatic structure.

[0008] A screwdriver bit sleeve is fitted onto the outer wall of the universal head.

[0009] Two clamping components are installed through the bit sleeve, and the two clamping components are arranged symmetrically.

[0010] The driving component is located on the outer wall of the bit sleeve and is used to drive the two clamping components to clamp towards the center.

[0011] Furthermore, the connector includes a fixing sleeve fitted onto one end of the extension rod; a fixing screw with one end threaded through the fixing sleeve and abutting against the outer wall of the extension rod; and a self-locking spring sleeve disposed on the end of the fixing sleeve away from the extension rod.

[0012] Furthermore, the clamping component includes two movable plates slidably disposed inside the bit sleeve; a spring disposed inside the bit sleeve and connected at both ends to the movable plates and the inner wall of the bit sleeve respectively; a clamping plate slidably passing through the outer wall of the bit sleeve and connected to the two movable plates; and a guide plate disposed on the outer wall of the clamping plate, the guide plate having an inclined surface.

[0013] Furthermore, the driving component includes a driving sleeve threaded onto the outer wall of the bit sleeve; a flat bearing disposed on one side of the driving sleeve; two push plates disposed on one side of the flat bearing, the push plates having inclined surfaces; and a sleeve frame disposed on the outer wall of the bit sleeve and slidably sleeved onto the outer wall of the push plates.

[0014] In summary, the beneficial effects of the above-described technical solutions conceived by this utility model compared with the prior art include:

[0015] The universal sleeve of this utility model allows the drive component to be screwed after the bit sleeve is fitted onto the outer wall of the screw, thereby driving the two clamping components to move closer together. This clamps and fixes the bit sleeve onto the outer wall of the screw, reinforcing the connection between the bit sleeve and the screw to prevent the sleeve from easily coming loose from the screw during the screw-tightening process, which would affect its use.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a universal sleeve, including an extension rod 1;

[0022] Connector 2 is detachably mounted at one end of extension rod 1;

[0023] Universal head 3 is located at the other end of extension rod 1, and the outer wall of universal head 3 has a prismatic structure.

[0024] Screwdriver sleeve 4 is fitted onto the outer wall of universal head 3;

[0025] Two clamping parts 5 are disposed through the bit sleeve 4, and the two clamping parts 5 are arranged symmetrically.

[0026] The driving component 6 is located on the outer wall of the bit sleeve 4 and is used to drive the two clamping components 5 to clamp towards the center.

[0027] In this embodiment, during use, the universal socket can be connected to the output end of the electric wrench via the connector 2, and the bit socket 4 can be fitted onto the outer wall of the screw. Through the insertion and engagement between the universal head 3 and the bit socket 4, the angle of the bit socket 4 can be adjusted. At the same time, the prismatic structure on the outer wall of the universal head 3 allows the bit socket 4 to rotate through the prismatic protrusions during the electric wrench's operation of the extension rod 1 and the universal head 3, thereby turning the screw inside the C-shaped purlin. After the bit socket 4 is fitted onto the outer wall of the screw, the drive component 6 can be turned to drive the two clamping components 5 to come together, so that the bit socket 4 is clamped and fixed on the outer wall of the screw, thus reinforcing the connection between the bit socket 4 and the screw to prevent the socket from easily coming loose from the screw during the screw turning process, which would affect its use.

[0028] Specifically, refer to Figure 1 The connector 2 includes a fixing sleeve 21 sleeved on one end of the extension rod 1; a fixing screw 22 with one end threaded through the fixing sleeve 21 and abutting against the outer wall of the extension rod 1; and a self-locking spring sleeve 23 disposed on the end of the fixing sleeve 21 away from the extension rod 1.

[0029] In this embodiment, before use, the fixing state of the extension rod 1 can be canceled by turning the fixing screw 22, so that the extension rod 1 can be removed and replaced with an extension rod 1 and bit sleeve 4 combination structure of different sizes and specifications. At the same time, the self-locking spring sleeve 23 can detachably fix the fixing sleeve 21 to the electric wrench (existing technology) through its own structure.

[0030] Specifically, refer to Figure 2-3 The clamping member 5 includes two movable plates 51 that are slidably disposed inside the bit sleeve 4; a spring 52 disposed inside the bit sleeve 4 and connected at both ends to the movable plates 51 and the inner wall of the bit sleeve 4 respectively; a clamping plate 53 that slides through the outer wall of the bit sleeve 4 and is connected to the two movable plates 51; and a guide plate 54 disposed on the outer wall of the clamping plate 53, the guide plate 54 having an inclined surface. The spring 52 is used to push the clamping plate 53 to reset after clamping and can prevent the clamping plate 53 from entering the bit sleeve 4 in advance, affecting the bit sleeve 4 being fitted outside the screw.

[0031] Specifically, refer to Figure 2-3The driving component 6 includes a driving sleeve 61 threaded onto the outer wall of the bit sleeve 4; a flat bearing 62 disposed on one side of the driving sleeve 61; two push plates 63 disposed on one side of the flat bearing 62, the push plates 63 having inclined surfaces; and a sleeve frame 64 disposed on the outer wall of the bit sleeve 4 and slidably sleeved on the outer wall of the push plates 63; the sleeve frame 64 can limit and guide the push plates 63 during movement to prevent the push plates 63 from leaving their relative position with the guide plate 54 as the flat bearing 62 and the driving sleeve 61 are screwed together.

[0032] In this embodiment, when it is necessary to reinforce the screw between the bit sleeve 4 and the screw, the drive sleeve 61 can be screwed first to allow the push plate 63 to move laterally toward the guide plate 54. After the push plate 63 contacts the guide plate 54, the inclined surfaces on both plates can guide the two clamping plates 53 to converge toward the center and compress the spring 52 to clamp and fix the screw. After the screw is screwed, the drive sleeve 61 can be screwed in the opposite direction, and the clamping plates 53 will return to their original position under the action of the spring 52.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
