[0031] See attached Figure 1-3As shown, the telescopic filter wrench of the embodiment of the utility model comprises a telescopic handheld component 1, a connecting arm 2, a clamp 3 for clamping an oil filter element, and a locking mechanism.

[0032] The retractable handheld assembly 1 includes a fixed handle 101 and a movable handle 102 . A bolt 4 is fixedly mounted on the front end of the fixed handle 101 . The movable handle 102 is movably mounted on the fixed handle 101 . A locking mechanism 5 is provided between the movable handle 102 and the fixed handle 101 .

[0033] A cylindrical connecting sleeve 205 is integrally formed at one end of the connecting arm 2, and a first pin 201 and a second pin 202 are rotatably installed at the other end of the connecting arm 2. The cylindrical connecting sleeve 205 is rotatably sleeved on the bolt 4. The first pin 201 is arranged at one end of the connecting arm 2 away from the cylindrical connecting sleeve 205, and the second pin 202 is located between the first pin 201 and the cylindrical connecting sleeve 205.

[0034] One end of the clamp 3 is fixedly mounted on the second pin 202 , and the other end of the clamp 3 is fixedly mounted with a connecting seat 204 , a mounting seat 203 is fixedly mounted on the connecting seat 204 , and the mounting seat 203 is fixedly connected to the first pin 201 .

[0035] The locking mechanism is used to lock the position between the fixed handle 101 and the movable handle 102, and adjust the overall length of the retractable handheld assembly 1, so that the torque when removing the oil filter element can be adjusted.

[0036] Specifically, in the embodiment of the utility model, a rectangular long strip-shaped adjusting slot 103 is provided along the length of the fixed handle 101 , and a plurality of teeth 104 arranged along the length direction thereof are integrally provided in the long strip-shaped adjusting slot 103 .

[0037] The locking mechanism 5 includes a connecting rod 501, a spring 503 and a locking gear 504. The connecting rod 501 is installed on the movable handle 102, and the connecting rod 501 is movably arranged to pass through the long strip adjustment slot 103. At the same time, a button 502 and a stopper 505 are fixedly installed at both ends of the connecting rod 501. The spring 503 is sleeved on the connecting rod 501, and the spring 503 is abutted between the button 502 and the outer wall of the movable handle 102. The locking gear 504 is fixedly sleeved on the connecting rod 501. Under the action of the spring 503, the locking gear 504 can enter the long strip adjustment slot 103 and mesh with the teeth 104. When the locking gear 504 meshes with the teeth 104, the stopper 505 abuts against the outer wall of the movable handle 102.

[0038] When in use, pressing the button 502 to compress the spring 503 can enable the locking gear 504 to disengage from the long strip adjusting slot 103 and separate from the teeth 104. At this time, the unlocking is achieved, and the movable handle 102 can be moved on the fixed handle 101 to adjust the overall length of the retractable handheld component 1. When the button 502 is released, the spring 503 resets and drives the locking gear 504 to enter the long strip adjusting slot 103 and engage with the teeth 104. At this time, the relative position of the movable handle 102 and the fixed handle 101 is locked.

[0039] In order to increase the overall length of the retractable handheld assembly 1 , the connecting rod 501 is disposed close to the front end of the movable handle 102 . In order to increase the compactness of the locking mechanism 5 and reduce the installation space, the locking gear 504 is disposed close to the stopper 505 .

[0040] In the embodiment of the utility model, in order to prevent the movable handle 102 from shaking relative to the fixed handle 101 to avoid affecting the use, the inner wall of the movable handle 102 and the outer wall of the fixed handle 101 are slidably fitted.

[0041] In order to increase the service life of the clamp 3, the clamp 3 is formed by bending a steel strip into an arc shape. In order to increase the friction between the clamp 3 and the oil filter element to avoid relative sliding, a plurality of anti-slip protrusions 301 are integrally provided on the inner side of the clamp 3.

[0042] In the embodiment of the utility model, for the convenience of use, the button 502 and the end surface of the stopper 505 away from the movable handle 102 are both configured as arc surface structures.

[0043] When the telescopic filter wrench of the utility model embodiment is used, the overall length of the telescopic hand-held component 1 is adjusted as needed. During adjustment, the button 502 is pressed to compress the spring 503 so that the locking gear 504 can be disengaged from the long strip adjustment slot 103 and separated from the teeth 104. At this time, the unlocking is achieved, and the movable handle 102 can be moved on the fixed handle 101 to adjust the overall length of the telescopic hand-held component 1. When the button 502 is released, the spring 503 resets and drives the locking gear 504 to enter the long strip adjustment slot 103 and mesh with the teeth 104. At this time, the relative positions of the movable handle 102 and the fixed handle 101 are locked. After the overall length of the telescopic hand-held component 1 is adjusted, the clamp 3 is put on the oil filter element for disassembly and assembly.

[0044] The above shows and describes the basic principles of the present invention. The above are only preferred embodiments of the present invention and are not intended to limit the present invention. The above embodiments and descriptions in the specification are only intended to illustrate the principles of the present invention.
