The electric bolt wrench body 1 is provided with a square shaft 11, and the side wall of the square shaft 11 is provided with a pin hole 111. The inner cavity shape of one end of the sleeve 2 matches the square shaft 11, and the inner cavity shape of the other end of the sleeve 2 matches the hexagonal head of the bolt.

[0004] When tightening the bolt, first, one end of the sleeve 2 is plugged into the square shaft 11; then, the other end of the sleeve 2 is buckled on the hexagonal head of the bolt; thereafter, the electric bolt wrench body 1 is started to drive the square shaft 11 to rotate, the square shaft 11 drives the sleeve 2 to rotate, and the sleeve 2 drives the hexagonal head of the bolt to rotate, thereby tightening the bolt.

[0005] As the sleeve is used for a long time, the inner wall of the sleeve is stained with dust and rust residue from the bolts. When cleaning the sleeve, the user usually blows directly at the inner cavity of the sleeve with his mouth. At this time, the dust and rust residue blown up are easily inhaled by the user, affecting the health of the user; and when blowing with the mouth, it is difficult to clean the stubborn dust and rust residue on the inner wall of the sleeve, making it inconvenient to clean.

[0006] Therefore, how to conveniently clean the sleeve and avoid endangering the health of users is a technical problem that needs to be solved at present. Utility Model Content

[0007] In view of the above-mentioned deficiencies in the prior art, the utility model provides an electric bolt wrench with a sleeve that is easy to clean. The utility model can facilitate the cleaning of the sleeve and avoid harming the health of users.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] An electric bolt wrench for easy cleaning of a sleeve comprises an electric bolt wrench body and a sleeve, wherein the electric bolt wrench body is provided with a square shaft, the side wall of the square shaft is provided with a pin hole, the electric bolt wrench body is also provided with an insertion rod, a cleaning seat is plugged and matched with the insertion rod, a square hole is provided at the end of the cleaning seat, the square hole is used for plugging and matching with the square shaft, a through hole is provided at the bottom of the square hole, a slide plate is provided in the square hole, the slide plate is connected to the bottom of the square hole through an elastic member, the elastic member is used to push the slide plate in a direction away from the through hole, a cleaning brush is provided on the side of the slide plate close to the through hole, the cleaning brush is matched with the through hole, a locking hole is provided on the side wall of the cleaning seat, the locking hole is connected with the square hole, a locking rod is provided in the locking hole, and the locking rod is plugged and matched with the pin hole.

[0010] Furthermore, the cleaning seat is provided with an insertion hole, a hole wall of the insertion hole is provided with a plurality of recesses, and the insertion rod is provided with a convex portion for cooperating with the recesses.

[0011] Furthermore, a guide groove is provided on the hole wall of the square hole, and the slide plate is provided with a guide portion, and the guide portion is slidably matched with the guide groove.

[0014] Furthermore, the locking hole is a screw hole, and the locking rod is a screw rod, and the screw rod is threadedly matched with the screw hole.

[0015] The utility model has the beneficial effects:

[0016] 1. The utility model can use the square shaft on the electric bolt wrench body to drive the cleaning seat to rotate, and the cleaning seat drives the cleaning brush to rotate, and the rotating cleaning brush can clean the inner wall of the sleeve. On the one hand, the cleaning brush is electrically driven, and the cleaning force is stronger than that of the user blowing with the mouth, and it can clean more thoroughly, is convenient to clean, and is more convenient for batch cleaning of the sleeve; on the other hand, the user does not need to blow with the mouth, so as to avoid the user from inhaling dust and rust residue on the inner wall of the sleeve, and avoid endangering the health of the user.

[0017] 2. Because when the sleeve is not cleaned, the cleaning seat can be plugged into the plug rod, and the plug rod is arranged on the electric bolt wrench body, so the cleaning seat can be followed by the electric bolt wrench body for use at any time without temporary search, thereby improving the flexibility of use.

[0018] 3. When the square shaft is pulled out of the square hole, the slide plate can be moved away from the through hole under the elastic force of the elastic member, and the slide plate drives the cleaning brush to move together, so that the cleaning brush returns to the square hole. At this time, not only the overall length of the cleaning brush and the cleaning seat can be shortened for easy storage, but also the cleaning brush can be surrounded and protected by the cleaning seat, which is beneficial to extend the service life of the cleaning brush and save replacement costs.

[0019] 4. After the square hole and the square shaft are plugged into place, the screw can be screwed down and inserted into the pin hole on the side wall of the square shaft. At this time, the plug-in state of the square hole and the square shaft can be stabilized. Therefore, when the square shaft rotates, the cleaning seat can rotate reliably with the square shaft to prevent the cleaning seat from detaching from the square shaft, thereby improving the reliability of use.

[0020] 5. Using a screw as the locking rod and a screw hole as the locking hole can make the matching of the locking rod and the locking hole simpler, facilitate material acquisition and processing, and help improve processing efficiency

[0021] 6. The setting of the guide groove and the guide part can increase the contact area between the square hole and the slide plate, and improve the stability of the slide plate sliding in the slide hole. Then, the cleaning brush can be stably driven by the slide plate, which improves the stability of the cleaning brush entering and exiting the through hole and avoids the cleaning brush from being skewed.

[0039] Example:

[0040] An electric bolt wrench with a sleeve that is easy to clean comprises an electric bolt wrench body 1 and a sleeve 2.

[0041] like Figure 6 As shown, a square shaft 11 is provided on the electric bolt wrench body 1 , and a pin hole 111 is provided on the side wall of the square shaft 11 .

[0042] like Figure 6 and Figure 7 As shown, the electric bolt wrench body 1 is also provided with an insertion rod 12, and the insertion rod 12 can be welded and fixed on the electric bolt wrench body 1. Fig. 9 As shown, the cleaning seat 3 is plugged into the plug rod 12. Specifically, as Figure 2-Figure 5 As shown, the cleaning seat 3 is provided with a plug hole 31 , and the plug hole 31 is used for plugging and matching with the plug rod 12 .

[0043] Further, such as Figure 4 and Figure 5 As shown, a plurality of recesses 311 are provided on the wall of the insertion hole 31. Figure 7 As shown, a convex portion 121 is provided on the insertion rod 12 , the convex portion 121 and the insertion rod 12 are an integral structure, and the convex portion 121 cooperates with the concave portion 311 .

[0044] When plugging and unplugging the cleaning seat 3 from the insertion rod 12, the user needs to use force to overcome the resistance between the protrusion 121 and the recessed portion 311 to plug and unplug the cleaning seat 3, so that the cleaning seat 3 cannot be easily plugged and unplugged, which is beneficial to improving the reliability and stability of the plug-in cooperation between the insertion rod 12 and the cleaning seat 3.

[0045] like Figure 2-Figure 5 As shown, a square hole 32 is provided at the end of the cleaning seat 3, and a through hole 321 is provided at the bottom of the square hole 32. A slide plate 4 is provided in the square hole 32, and the slide plate 4 can slide in the square hole 32 along a direction close to the through hole 321 or away from the through hole 321.

[0046] like Figure 4 As shown, an elastic member 5 is also provided in the square hole 32. The elastic member 5 can be a spring. One end of the elastic member 5 is connected to the slide plate 4, and the other end of the elastic member 5 is connected to the bottom of the square hole 32. The elastic member 5 is used to push the slide plate 4 away from the through hole 321.

[0047] like Figure 4 and Figure 5 As shown, the slide plate 4 is provided with a cleaning brush 6 on one side close to the through hole 321. The cleaning brush 6 includes a brush shaft 61 and bristles 62. One end of the brush shaft 61 is welded and fixed to the slide plate 4. The surface of the brush shaft 61 is provided with bristles 62. When the slide plate 4 overcomes the elastic force of the elastic member 5 and approaches the through hole 321, the slide plate 4 drives the cleaning brush 6 to move together, and the cleaning brush 6 can extend from the through hole 321.

[0048] When cleaning the sleeve 2: first, the user pulls the cleaning seat 3 off the insertion rod 12; then, Figure 8 As shown, the user plugs the square hole 32 on the cleaning seat 3 into the square shaft 11 on the electric bolt wrench body 1. During the plugging process, the square shaft 11 overcomes the elastic force of the elastic member 5 and pushes the slide plate 4. The slide plate 4 drives the cleaning brush 6 to approach the through hole 321, so that the cleaning brush 6 extends from the through hole 321; then, the sleeve 2 to be cleaned is put on the outside of the cleaning brush 6; finally, the user holds the outer wall of the sleeve 2 with one hand and starts the electric bolt wrench body 1 with the other hand. The electric bolt wrench body 1 drives the square shaft 11 to rotate, the square shaft 11 drives the cleaning seat 3 to rotate, the cleaning seat 3 drives the cleaning brush 6 to rotate, and the cleaning brush 6 brushes the inner wall of the sleeve 2 to clean the dust and rust residue on the inner wall of the sleeve 2.

[0049] Through the above process, it can be known that in this embodiment, the square shaft 11 on the electric bolt wrench body 1 can be used to drive the cleaning seat 3 to rotate, and the cleaning seat 3 drives the cleaning brush 6 to rotate, and the rotating cleaning brush 6 can clean the inner wall of the sleeve 2. On the one hand, the cleaning brush 6 is electrically driven, and the cleaning force is stronger than that of the user blowing with the mouth, and it can clean more thoroughly, is convenient to clean, and is more convenient to clean the sleeve 2 in batches; on the other hand, there is no need for the user to blow with the mouth, so that the user can avoid inhaling dust and rust residue on the inner wall of the sleeve 2, and avoid endangering the health of the user.

[0050] And, if Fig. 9 As shown, because the cleaning seat 3 can be plugged into the plug rod 12 when the sleeve 2 is not cleaned, and the plug rod 12 is arranged on the electric bolt wrench body 1, the cleaning seat 3 can follow the electric bolt wrench body 1 so that it can be taken at any time without temporary searching, thereby improving the flexibility of use.

[0051] Furthermore, if Figure 2-Figure 5 As shown, when the square shaft 11 is pulled out from the square hole 32, the slide plate 4 can be moved away from the through hole 321 under the elastic force of the elastic member 5, and the slide plate 4 drives the cleaning brush 6 to move together, so that the cleaning brush 6 is retracted into the square hole 32. At this time, not only the overall length of the cleaning brush 6 and the cleaning seat 3 can be shortened for easy storage, but also the cleaning brush 6 can be surrounded and protected by the cleaning seat 3, which is beneficial to extend the service life of the cleaning brush 6 and save replacement costs.

[0052] like Figure 4 and Figure 5 As shown, further, the side wall of the cleaning seat 3 is provided with a locking hole 33, the locking hole 33 is connected to the square hole 32, and the locking hole 33 is a screw hole. A locking rod 331 is provided in the locking hole 33, and the locking rod 331 is a screw rod, and the screw rod is threadedly matched with the screw hole.

[0053] After the square hole 32 and the square shaft 11 are plugged into place, the screw can be screwed downward and inserted into the pin hole 111 on the side wall of the square shaft 11. At this time, the plug-in state of the square hole 32 and the square shaft 11 can be stabilized. Therefore, when the square shaft 11 rotates, the cleaning seat 3 can rotate reliably with the square shaft 11, preventing the cleaning seat 3 from separating from the square shaft 11, thereby improving the reliability of use.

[0054] Furthermore, by using a screw rod as the locking rod 331 and a screw hole as the locking hole 33 , the locking rod 331 and the locking hole 33 can be matched more simply, which is convenient for material acquisition and processing, and is conducive to improving processing efficiency.

[0055] Further, such as Figure 4 and Figure 5 As shown, a guide groove 322 is provided on the hole wall of the square hole 32 , a guide portion 41 is provided on the slide plate 4 , the guide portion 41 is slidably matched with the guide groove 322 , and the elastic member 5 is arranged in the guide groove 322 .

[0056] The setting of the guide groove 322 and the guide part 41 can increase the contact area between the square hole 32 and the slide plate 4, and improve the stability of the slide plate 4 sliding in the slide hole. Then, the cleaning brush 6 can be stably driven by the slide plate 4, thereby improving the stability of the cleaning brush 6 entering and exiting the through hole 321 and avoiding the cleaning brush 6 from being skewed.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
