Detailed Description

The utility model is further described below in connection with specific embodiments.

The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments, and all other embodiments obtained by those skilled in the art without making any creative effort based on the embodiments in the present utility model are all within the protection scope of the present utility model.

Example 1

A wrench is shown in fig. 1, and comprises a wrench handle 1 and a sleeve head 2 fixedly connected with the wrench handle 1, wherein the sleeve head 2 is sleeved on the outer circumferential side of a hexagonal bolt 3, the inner side wall of the sleeve head 2 is subjected to anti-skid treatment, and the friction force between the sleeve head 2 and the hexagonal bolt 3 is increased. The wrench handle 1 is of a hollow structure, an adjusting rod 4 is rotatably connected inside, and one end of the adjusting rod 4 is contacted with the hexagon bolt 3. The adjusting rod 4 comprises a push rod 41 and a threaded rod 42 which are fixedly connected. The ejector rod 41 is abutted with the hexagonal bolt 3, the inner side wall of the wrench handle 1 is provided with internal threads, and the threaded rod 42 is in threaded connection with the inner side wall of the wrench handle 1. One end of the threaded rod 42 extends beyond the trigger handle 1 for ease of adjustment. When the wrench is used, the hexagonal bolt 3 is placed in the sleeve head 2, the threaded rod 42 is rotated, the ejector rod 41 moves to the hexagonal bolt 3 to be abutted against the hexagonal bolt 3, and the wrench handle 1 is rotated to complete the disassembly of the hexagonal bolt 3; the hexagonal bolt 3 can be removed by rotating the threaded rod 42 in the opposite direction.

In order to better adjust and fix the hexagonal bolt 3, the end of the threaded rod 42 extending from the wrench handle 1 can be provided with an adjusting pin 5, so that force application is facilitated, and the operation is more flexible and accurate.

Example 2

As shown in fig. 2, this embodiment is different from embodiment 1 in that: the ejector rod 41 is provided with a clamping block 6 with adjustable opening at one end close to the sleeve head 2. The clamping block 6 adopts the V-shaped design, and the clamping block 6 comprises two clamping legs 61, and two clamping legs 61 one end all articulates the tip at ejector pin 41, is equipped with telescopic link 62 between two clamping legs 61, can adjust the degree of opening and shutting between two clamping legs 61 through the flexible of telescopic link 62.

With this structure, the user can flexibly adjust the opening degree of the clamp block 6 according to the size and shape of the bolt, so that it is tightly fixed on the bolt, and provide sufficient friction force to complete the disassembling or assembling operation of the bolt. The clamping block 6 with adjustable opening can ensure the close fit of the wrench and the deformed hexagon bolt 3, so that the working efficiency and the operation safety are improved.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
