AI Technical Summary
In the maintenance operations of the chemical industry, the tap wrench used is prone to pop out at the moment of tapping, which increases the possibility of personal injury accidents. Existing protective measures such as binding wire or string are not firm, and the handle opening design has the problem of insufficient safety performance.
A bent handle type tap wrench is designed, with the handle being a bent handle, the angle between the bend is 30°, and a mounting hole is installed on the handle to fix the draw rope, and a buckle and a latch structure are installed on the draw rope to achieve the stability of the engagement through magnet attracting the latch plate, reducing the friction and breaking risks of the draw rope.
Through the design of the bent handle and 30° angle, the stress during tap is increased to concentrate on the wrench to prevent slippage accidents; the engaging stable structure effectively prevents the wrench from popping out during use, improving the safety of use.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of percussion wrenches, in particular to a bent-handle percussion wrench. Background Art
[0002] Maintenance work is frequent in the chemical industry, and the percussion wrenches used to lock large flanges often generate stress at the moment of percussion, causing the wrenches to pop out and cause personal injury accidents to the maintenance personnel. When working at high places such as towers, the percussion wrenches used may pop out and fall from a height during the operation, increasing the possibility of accidents.
[0003] At present, some maintenance personnel will tie a wire or a small rope to the handle of the percussion wrench when using it to prevent the percussion wrench from flying out and injuring people at the moment of percussion. However, the wire and small rope tied to the handle of most percussion wrenches are not secure. Some percussion wrenches also have a hole at the end of the handle. When in use, pulling it with a thin rope can effectively prevent the wrench from popping out and injuring people. However, the hole at the end of the wrench is the force point for percussion, and the hole may be easily deformed. The safety performance needs to be further improved. Utility Model Content
[0004] The utility model aims to solve the problems raised in the above-mentioned background technology and provides a bent-handle striking wrench.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A striking block fixedly connected to the handle;
[0010] The handle is a curved handle, and the angle of the curved portion of the handle is α;
[0011] The angle α is 30°.
[0012] Preferably, a mounting hole is provided on the handle, a drawstring is fixedly connected to the mounting hole, and a buckle is provided on the drawstring.
[0013] Furthermore, the pull rope is connected to a first clamping plate and a second clamping plate, and the first clamping plate and the second clamping plate are fixedly connected.
[0014] Furthermore, the first clamping plate and the second clamping plate are both threadedly connected with screw rods, and the screw rods and the pull ropes are against each other.
[0015] Furthermore, a clamping rod is fixedly connected to the first clamping plate, and a clamping hole is provided on the second clamping plate, and the clamping rod matches the clamping hole.
[0016] Furthermore, a first magnet is fixedly connected to the clamping rod, and a second magnet is fixedly connected to the clamping hole, and the first magnet and the second magnet attract each other.
[0017] Compared with the prior art, the utility model provides a bent-handle percussion wrench, which has the following beneficial effects:
[0018] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The utility model sets the handle as a curved handle. Compared with the ordinary straight-handled striking wrench, the curved handle can make more force fall on the striking wrench when the sledgehammer strikes, thereby preventing the sledgehammer from slipping and causing accidents when striking. The angle of the curved portion is set to 30°, which is more suitable for environments where operations are blocked by surrounding objects compared to the ordinary straight-handled design, and it is easier to hit the striking block.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0026] Embodiment 1:
[0027] Reference Figure 1-Figure 5 , a bent handle type percussion wrench, comprising:
[0028] Handle 1;
[0029] A wrench head 2 is fixedly connected to the handle 1;
[0030] A striking block 3 is fixedly connected to the handle 1;
[0031] The handle 1 is a curved handle, and the angle of the curved portion of the handle 1 is α;
[0032] The angle α is 30°.
[0033] The handle 1 is provided with a mounting hole 101 , a drawstring 4 is fixedly connected in the mounting hole 101 , and a buckle 401 is provided on the drawstring 4 .
[0034] Reference Figure 1 , Figure 5 During use, the staff can put the buckle 401 on the wrist, thereby effectively preventing the wrench from falling.
[0035] The pull rope 4 is connected to a first clamping plate 5 and a second clamping plate 6 , and the first clamping plate 5 and the second clamping plate 6 are fixedly connected.
[0036] The first clamping plate 5 and the second clamping plate 6 are both threadedly connected with a screw rod 8 , and the screw rod 8 and the pull rope 4 are against each other.
[0037] A clamping rod 501 is fixedly connected to the first clamping plate 5 , and a clamping hole 601 is provided on the second clamping plate 6 . The clamping rod 501 and the clamping hole 601 match each other.
[0038] A first magnet 5011 is fixedly connected to the clamping rod 501 , and a second magnet 6011 is fixedly connected to the clamping hole 601 . The first magnet 5011 and the second magnet 6011 attract each other.
[0039] Reference Figure 4 The first magnet 5011 and the second magnet 6011 are attracted to each other, thereby ensuring the engagement stability of the first clamping plate 5 and the second clamping plate 6.
[0040] Reference Figure 4 The first clamping plate 5 and the second clamping plate 6 are both provided with mounting grooves 7 for mounting the pull rope 4 .
[0041] Reference Figure 1-Figure 5Before use, the pull rope 4 is passed through the first clamping plate 5 and the second clamping plate 6 respectively. The staff can pass the pull rope 4 through the installation hole 101, leave a safe length, and then use a wrench to tighten the screw 8 and make it against the pull rope 4, thereby pressing the pull rope 4, and then the first clamping plate 5 and the second clamping plate 6 are opposite to each other, so that the clamping rod 501 is clamped into the clamping hole 601, thereby fixing the pull rope 4.
[0042] Reference Figure 3 The mounting hole 101 is provided with an arc groove, and the arc groove can reduce the friction on the pull rope 4 and reduce the possibility of the pull rope 4 breaking.
[0043] Reference Figure 1-Figure 5 During use, the staff takes the handle 1 and puts the wrench head 2 on the nut to be screwed. After placing it, the staff can hit the knocking block 3 with a knocking hammer, thereby hammering the handle 1 to rotate, and then screwing the nut to be screwed.
[0044] Reference Figure 1 By setting the handle 1 to be a bent handle, compared with a normal straight-handled striking wrench, the bent handle can make more force fall on the striking wrench when the sledgehammer strikes, preventing the sledgehammer from slipping and causing accidents when striking, and the angle of the bent portion is set to 30°. Compared with the normal straight-handled design, it is more suitable for an environment where the operation is blocked by surrounding objects, and it is easier to strike the striking block 3.
