Detailed Description
The principles and features of the present invention are described below in conjunction with the accompanying fig. 1-5, which are provided by way of example only to illustrate the present invention and not to limit the scope of the present invention.
A telescopic type stress application pipe wrench comprises an inner rod 1, an outer rod 2, a fixed jaw 3, a movable jaw 4, a movable nut 5, a locking sleeve 6 and a clamping ring 7.
One end of the inner rod 1 extends into the inner cavity of the outer rod 2, and the inner rod 1 and the outer rod 2 are connected in a sleeved mode to form a clamp handle 8. The length of the forceps handle 8 can be changed by adjusting the length of the inner rod 1 extending into the inner cavity of the outer rod 2. Thus, the handles 8 are of the telescopic type. The end of the outer rod 2 is provided with an enlarged end 20. The sides of the enlarged end 20 are straight, as shown at B in fig. 1, to increase the support strength. The fixed jaw 3 is connected to one side of the expansion end 20, the movable jaw 4 comprises a hook head part 9 and a thread part 10 which are integrally formed, and the movable jaw 4 is approximately 7-shaped. The thread part 10 is connected with the expansion end 20 in a sliding mode and is in threaded connection with the movable nut 5, and the movable nut 5 is meshed with the thread part 10 through the sawtooth-shaped threads, so that the meshing strength is improved. The hook head 9 extends to be opposite to the fixed jaw 3. The opening size of the hook head part 9 and the fixed jaw 3 can be adjusted by rotating the movable nut 5. The end parts of the fixed jaw 3 and the movable jaw 4 are respectively provided with a guide surface 19, so that a workpiece can be clamped conveniently. The lock sleeve 6 is in threaded connection with the other end of the outer rod 2, the snap ring 7 is coaxially sleeved outside the inner rod 1 and fixed at the end part of the outer rod 2 through the lock sleeve 6. Under the action of external force, the snap ring 7 can slide relative to the inner rod 1, so that the length of the handle 8 is changed; when the external force disappears, the inner rod 1 is fixed relative to the outer rod 2 under the action of the clamping ring 7, and then the length of the handle 8 is fixed.
The locking sleeve 6 comprises a connecting portion 11 and a flange portion 12 which are integrally formed, and the flange portion 12 is arranged at one end of the connecting portion 11. The connecting portion 11 is cylindrical and has a screw thread on an inner surface. The flange portion 12 is provided with an inner hole through which the inner rod 1 is inserted or passed. The locking sleeve 6 is in threaded connection with the outer rod 2. The snap ring 7 is pressed and fixed between the flange portion 12 and the end surface of the outer rod 2. The snap ring 7 is circular, the snap ring 7 is provided with opening 13, the snap ring 7 forms interference fit with interior pole 1, and only when external force was big enough, the pole 1 made its and snap ring 7 take place relative slip in can dragging.
The inner rod 1 and the outer rod 2 are both of circular tube structures. A plug 14 is clamped at one end of the inner rod 1, and the plug 14 is made of plastic. The other end of the inner rod 1 is communicated with the inner cavity of the outer rod 2. The inner cavity of the outer rod 2 can be filled with lubricating oil by opening the plug 14. The lubricating oil can prevent the clamping ring 7 and the inner rod 1 from rusting each other for a long time. The inner rod 1 comprises a first rod part 15, a second rod part 16 anda handle portion 17. The first rod part 15 and the second rod part 16 are integrally formed, and the second rod part 16 is in threaded connection with the handle part 17. The second rod portion 16 is provided with protrusions 18 at both ends thereof, respectively. The inner diameter of the outer rod 2 is defined as D1The first rod part 15 has an outer diameter D2The second shaft portion 16 has an outer diameter D3The outer diameter of the projection 18 is D4The inner diameter of the inner hole is D5Wherein D is5＜D2＜D1，D3＜D5，D5＜D4. The assembling sequence of the forceps handle 8 is as follows: 1) firstly, the locking sleeve 6 is penetrated on the first rod part 15/the second rod part 16; 2) then the handle part 17 is screwed on the second rod part 16; 3) connecting the snap ring 7 to the first rod portion 15/the second rod portion 16; 4) one end of the inner rod 1 is inserted into the inner cavity of the outer rod 2, and the locking sleeve 6 is screwed on the outer rod 2. D5＜D2＜D1The inner rod 1 can be prevented from being separated from the outer rod 2 under the condition that the locking sleeve 6 is not removed, so that a first limit is formed; d5＜D4The handle portion 17 is prevented from penetrating into the inner cavity of the outer rod 2, forming a second limit.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
