[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] refer to Figure 1 and Figure 2 The filter disassembly and assembly tool includes: a connector assembly P, a fixing seat M, and two clamping members 1 (which can be a steel structure). The two clamping members 1 are relatively arranged along a first direction (X-axis direction) and are slidably connected to the fixing seat M; the connector assembly P is rotationally connected to the fixing seat M, is transmission-connected to the two clamping members 1, and is used to convert the rotational motion of the connector assembly P into a linear motion of the two clamping members 1 approaching and moving away from each other; each clamping member 1 is provided with a locking assembly 4, and the locking assembly 4 is used to lock the corresponding clamping member 1 with the fixing seat M.

[0022] When the filter 200 needs to be loaded and unloaded, the filter 200 is placed between the two clamping members 1, and the connector assembly P is rotated in one direction to drive the two clamping members 1 closer to each other to clamp the filter 200. The corresponding clamping member 1 is locked with the fixing seat M by the locking assembly 4 to keep the two clamping members 1 clamping the filter 200, providing a large torque support for the removal and installation of the filter 200, and then tightening it to the corresponding position of the engine, or unscrewing it from the engine; and then rotating the connecting assembly in the opposite direction to drive the two clamping members 1 away from each other to loosen the filter 200. As described above, the clamping and loosening of the filter 200 by the two clamping members 1, as well as the rotational loading and unloading of the filter 200, can be achieved by rotating the connector assembly P, and the operation is convenient and simple.

[0023] In a specific embodiment, the connector assembly P includes a first connector 8 and a second connector 7 that are coaxially arranged, and the second connector 7 is sleeved inside the first connector 8. The second connector 7 can specifically pass through the center hole 81 of the first connector 8 to ensure that the second connector 7 is positioned at the center of the first connector 8. The middle part of the first connector 8 is rotatably connected to the fixing seat M around the axis of the second direction (Y-axis direction), such as the second connector 7 and the first connector 8 pass through the center hole 61 of the upper fixing plate 6 together; the outer periphery of the first connector 8 has a first characteristic structure 82, and the first connector 8 is on the periphery. The outer periphery of the head 8 is not affected by the second connector 7, and a first characteristic structure 82 that cooperates with a wrench can be set to drive the first connector 8 to rotate through the first characteristic structure 82. The inner periphery of the second connector 7 is not blocked by the first connector 8. The inner periphery of the second connector 7 has a second characteristic structure 72. The wrench matches the second connector 7 by connecting the second characteristic structure 72 to drive the second connector 7 to rotate; the two ends of the first connector 8 are respectively rotatably connected to the two clamping members 1, and the two ends of the second connector 7 are respectively rotatably connected to the two clamping members 1; wherein, the second direction (Y-axis direction) is perpendicular to the first direction (X-axis direction). The rotational connection positions of the first connector 8 and the two clamping members 1 (refer to the first sliding hole 13) are mutually aligned in the first direction; the rotational connection positions of the second connector 7 and the two clamping members 1 (refer to the second sliding hole 12) are mutually staggered in the first direction. When removing the filter 200, turning the wrench (such as a ratchet wrench) counterclockwise can make the second connector 7 rotate counterclockwise, drive the two clamping members 1 to move toward each other, and clamp the filter 200; when installing the filter 200, turning the wrench (such as a ratchet wrench) clockwise can make the first connector 8 rotate clockwise, drive the two clamping members 1 to move toward each other, and clamp the filter 200. The first connector 8 and the second connector 7 have clear division of labor in different scenarios. The first connector 8 is operated clockwise and the second connector 7 is operated counterclockwise to respectively install and remove the filter 200.

[0024] The filter disassembly and assembly tool has a forward and reverse bidirectional design. By replacing the socket of the ratchet wrench, the filter 200 can be installed self-lockingly, which greatly improves the efficiency of maintenance operations.

[0025] In a specific embodiment, the first characteristic structure 82 is an outer hexagonal structure, and the second characteristic structure 72 is an inner square structure, so as to perform feature matching with the ratchet wrench to achieve a stable connection.

[0026] In a specific embodiment, the first connecting head 8 is provided with a first cylindrical head 83 at both ends, and the second connecting head 7 is provided with a second cylindrical head 71 at both ends; each clamping member 1 is provided with a first sliding hole 13 and a second sliding hole 12, and the first sliding hole 13 and the second sliding hole 12 both extend along the second direction (Y-axis direction); the first cylindrical head 83 is rotatably connected to the first sliding hole 13 one by one, and the second cylindrical head 71 is rotatably connected to the second sliding hole 12 one by one. When the first connecting head 8 is rotated clockwise by a ratchet wrench, the first cylindrical head 83 rotates in the first sliding hole 13, and the angle between the first connecting head 8 and the two clamping members 1 is adjusted with a small resistance, ensuring that the clamping members 1 do not rotate when they approach each other; when the second connecting head 7 is rotated counterclockwise by a ratchet wrench, the second cylindrical head 71 rotates in the second sliding hole 12, and the angle between the second cylindrical head 71 and the two clamping members 1 is adjusted with a small resistance, ensuring that the clamping members 1 do not rotate when they approach each other.

[0027] In a specific embodiment, the two clamping members 1 each include a guide plate b and an arc plate a. The concave sides of the two arc plates a are arranged relative to each other to match the circular cross-section of the filter 200, increase the contact area, and achieve stable clamping. The guide plate b is connected to the concave side of the arc plate a. Each guide plate b slides with the fixing seat M along the first direction (X-axis direction) to achieve stable sliding cooperation between the clamping member 1 and the fixing seat M; when the clamping member 1 is provided with a first sliding hole 13 and a second sliding hole 12, the first sliding hole 13 and the second sliding hole 12 are both located on the guide plate b, and the guide plate b can provide a sufficiently large span space for the first sliding hole 13 and the second sliding hole 12.

[0028] In a specific embodiment, the concave sides of the arc-shaped plate a are provided with anti-skid grooves 14 to increase the friction with the filter 200 and prevent slipping.

[0029] In a specific embodiment, the guide plate b has locking teeth 11 arranged along the first direction (X-axis direction), and the locking assembly 4 includes a one-way locking pin 42 and an elastic member 41; when the one-way locking pin 42 is in the first position, the one-way locking pin 42 is engaged with the locking teeth 11; when the one-way locking pin 42 is in the second position, the one-way locking pin 42 is separated from the locking teeth 11; the elastic member 41 provides the one-way locking pin 42 with an elastic reset force to return from the second position to the first position. When the two clamping members 1 approach each other, a row of multiple locking teeth 11 continuously push the one-way locking pin 42 away to move forward. When the locking teeth 11 stop, under the action of the elastic member 41, the one-way locking pin 42 is stuck with the locking teeth 11. The one-way locking pin 42 and the locking teeth 11 are one-way matched, which can prevent the locking teeth 11 from retreating and achieve locking. When the two clamping members 1 need to be removed from the filter 200 , unlocking can be achieved by simply pulling out the one-way locking pin 42 .

[0030] In a specific embodiment, the fixed seat M includes a seat body 5 and a top cover 6, the seat body 5 has a slide groove V, the guide plate b is slidably fitted in the slide groove V to achieve sliding in the first direction in the slide groove V, and the top cover 6 is locked at the top opening of the slide groove V of the seat body 5 by fasteners such as fastening screws 2; the connecting head assembly P passes through the through hole 61 of the top cover 6 and is rotatably connected to the top cover 6 to achieve limiting the connecting head assembly P in the first direction and the second direction.

[0031] In a specific embodiment, the filter disassembly and assembly tool further includes a pre-clamping elastic component, which is used to provide a pre-tightening force for the two clamping members 1 to approach each other. The pre-clamping elastic component may specifically include a coil spring 3 symmetrically arranged on both sides of the two clamping members 1, and the two coil springs 3 tighten the two clamping members 1 to achieve preliminary elastic pre-tightening and preliminary positioning when the filter 200 is sleeved, so as to facilitate the subsequent operation.
