[0049] In another embodiment provided by the present invention, a rack 100 is disposed at the upper end of the first rod 10 and the upper end of the third rod 12, the fixed gear 20 is meshed with the rack 100, and the side edges of the second rod 11 and the fourth rod 13 are rough surfaces;

[0050] The specific implementation is as follows: the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 form a rectangle to surround and reinforce the outer side of the template, and the fixed gear 20 is meshed with the rack 100, and when the fixed gear 20 is rotated, the locking spring 22 squeezes the locking rod 21 to snap into the slots 201 at different positions on the side of the fixed gear 20, so that the fixed gear 20 drives the third rod body 12 and the fourth rod body 13 to move unidirectionally outside the first rod body 10 and the third rod body 12 respectively through the sliding sleeve 14, so that the third rod body 12 slides along the first rod body 10 and gradually approaches the second rod body 11 , the fourth rod 13 gradually approaches the first rod 10 along the third rod 12 and the second rod 11, so that the first rod 10, the second rod 11, the third rod 12 and the fourth rod 13 can reinforce the outer side of the template, and at the same time, the squeezing rod 33 is rotated by the handle 34, so that the squeezing rod 33 squeezes the sides of the second rod 11 and the fourth rod 13 respectively through the two supporting rods 31, and when the supporting rod 31 squeezes and locks the sides of the second rod 11 and the fourth rod 13, the rough surfaces of the sides of the second rod 11 and the fourth rod 13 avoid or even reduce the sliding between the two and the slider 30.

[0051] In another embodiment provided by the present invention, the locking assembly 2 further includes a rotating rod 24, the rotating rod 24 is connected to the fixed gear 20, a lever 25 is slidably provided at one end of the rotating rod 24 close to the fixed gear 20, a return spring 26 is provided between the lever 25 and the rotating rod 24, an inclined surface is provided at one end of the lever 25 close to the fixed gear 20, and a second pull rod 27 is provided at one end of the lever 25 away from the fixed gear 20;

[0052] The specific implementation method is as follows: before the sliding sleeve 14 is inserted into the third rod body 12 and the fourth rod body 13, the first pull rod 23 and the second pull rod 27 are pulled in the direction away from the fixed gear 20, thereby releasing the lock on the locking rod 21 and the lever 25, making it easier for the sliding sleeve 14 to be inserted into the sleeve; when the third rod body 12 and the fourth rod body 13 are close to and fit on the outer side of the template, the first pull rod 23 and the second pull rod 27 are released, and the rotating rod 24 is rotated at this time, so that the rotating rod 24 drives the fixed gear 20 to mesh and move with the rack 100, so that the rotating rod 24 drives the third rod body 12 and the fourth rod body 13 to move along the first rod body 10 and the third rod body 12 respectively through the sliding sleeve 14, and the locking rod 21 and the lever 25 are unlocked at this time. The tightening spring 22 squeezes the locking rod 21 into the slot 201 to prevent the fixed gear 20 from rotating in the opposite direction. When the rotating rod 24 drives the fixed gear 20 to rotate, the return spring 26 squeezes the lever 25 to move toward the outside of the rotating rod 24, so that the lever 25 can get stuck in the slot 201 on the side of the fixed gear 20 to drive the fixed gear 20 to rotate. When the rotating rod 24 rotates in the opposite direction, the inclined surface of the lever 25 can make the lever 25 and the multiple slots 201 continuously get stuck in and slide out without driving the fixed gear 20 to rotate in the opposite direction. The inclined surfaces arranged on the locking rod 21 and the lever 25 can ensure that the fixed gear 20 rotates in the direction close to the template without moving in the opposite direction.

[0054] The specific implementation is as follows: the squeezing rod 33 is rotated by the handle 34 so that the squeezing rod 33 squeezes the two abutting rods 31 at the same time so as to lock and fix the second rod body 11 and the fourth rod body 13 in the slider 30 at the same time. The squeezing rod 33 can drive the ratchet 35 to rotate while rotating. At this time, the pawl 37 can be separated from the teeth of the ratchet 35 and slide outside the ratchet 35. When the second rod body 11 and the fourth rod body 13 are squeezed and locked by the abutting rod 31 in the slider 30, the pawl 37 can lock the squeezing rod 33 through the ratchet 35, thereby locking the second rod body 11 and the fourth rod body 13. The body 13 is locked and fixed in the slider 30 to prevent the second rod body 11 and the fourth rod body 13 from sliding in the slider 30 and causing the template to loosen; when removing, when the paddle 39 is pushed in the direction away from the fixed gear 20, the paddle 39 drives the pawl 37 to squeeze the clamping spring 38 to release the lock on the ratchet 35, so that the handle 34 drives the squeezing rod 33 to rotate in the opposite direction and reset, thereby resetting the push rod 31, so that the push rod 31 releases the lock on the second rod body 11 and the fourth rod body 13, making it easy to remove the fourth rod body 13 from the second rod body 11.

[0055] In another embodiment provided by the present invention, two extrusion blocks 330 are arranged outside the extrusion rod 33, each extrusion block 330 is fitted with a stop rod 31, and the distance between the edge of the extrusion block 330 and the central axis of the extrusion rod 33 gradually increases;

[0056] The specific implementation is as follows: the extrusion block 330 fits with the push rod 31, and the distance between the edge of the extrusion block 330 and the central axis of the extrusion rod 33 gradually increases. When the extrusion rod 33 rotates, the extrusion block 330 can squeeze the push rod 31 so that the push rod 31 locks and fixes the second rod body 11 or the fourth rod body 13 in the slider 30, and when the extrusion rod 33 is rotated in the opposite direction, the extrusion block 330 gradually moves away from the push rod 31. At this time, the connecting spring 32 drives the push rod 31 to reset and release the lock on the second rod body 11 or the fourth rod body 13, making it convenient to remove the second rod body 11 or the fourth rod body 13 from the slider 30.

After the total length between the support rod 40 and the sliding rod 42 is adjusted, the adjusting spring 44 can squeeze the adjusting rod 43 to move outward along the sliding rod 42, so that the adjusting rod 43 is stuck in the clamping holes at different positions. In this way, the total length between the support rod 40 and the sliding rod 42 is adjusted to adapt to and fix the adjacent first rod body 10, the second rod body 11, the third rod body 12 or the fourth rod body 13 at different positions.

[0062] The specific implementation is as follows: the extension rod 50 is installed and connected with the threaded hole through the threaded column 501, and when connected, the sliding grooves at the free ends of the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 are aligned and connected with the sliding grooves provided on the extension rod 50. At this time, the threaded rod 51 is rotated so that the threaded rod 51 drives the clamping block 52 to slide along the sliding groove of the extension rod 50 toward the sliding grooves of the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13, and the pin column is clamped into the clamping hole of the clamping block 52. At this time, the clamping block 52 is in the middle of the connection between the extension rod 50 and the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13, so that the clamping block 52 can clamp and limit the installed extension rod 50 to prevent the extension rod 50 from rotating and moving after installation.

[0063] In another embodiment provided by the present invention, the shape of the extension rod 50 is the same as the shape of the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 connected thereto;

[0064] The specific implementation is as follows: the outer shape of the extension rod 50 is respectively the same as the outer shapes of the connected first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13, so that the locking assembly 2, the fixing assembly 3 and the supporting assembly 4 can work normally, and avoid the situation where the locking assembly 2, the fixing assembly 3 and the supporting assembly 4 are difficult to fully reinforce the template during use due to the difference in the outer shape of the extension rod 50 and the connected first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13.

[0065] Working principle: Before using the reinforcement device, assemble the template first, and then use the reinforcement device to clamp and fix the outer side of the template. Specifically, according to the size of the template, fit the first rod 10 and the second rod 11 that are fixed as a whole and perpendicular to each other to a corner of the template, and then insert the third rod 12 through the sliding sleeve 14 to the outside of the first rod 10, and then insert the fourth rod 13 and the second rod 11 into the slider 30 in sequence. When the fourth rod 13 and the second rod 11 are inserted into the slider 30, the other end of the fourth rod 13 is placed on top of the second rod 11, and the second rod 11 is inserted into the slider 30 at the same time. , the fourth rod body 13 is inserted into the outer side of the third rod body 12 through the sliding sleeve 14, so that the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 form a rectangle to surround and reinforce the outer side of the template, and when the first rod body 10 and the third rod body 12 are inserted into the sliding sleeve 14, the first pull rod 23 and the second pull rod 27 are pulled outward at the same time, so that the locking rod 21 and the shifting rod 25 are away from the fixed gear 20, so that the fixed gear 20 can rotate arbitrarily around its axis, which is convenient for inserting the sliding sleeve 14, and avoids the situation where the locking rod 21 and the shifting rod 25 cause the fixed gear 20 to be locked and fixed and difficult to insert;

[0066] When the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 surround and reinforce the outer side of the template, the fixed gear 20 is meshed with the rack 100, and when the fixed gear 20 is rotated, the locking spring 22 squeezes the locking rod 21 and snaps into the slots 201 at different positions on the side of the fixed gear 20, so that the fixed gear 20 drives the third rod body 12 and the fourth rod body 13 to move unidirectionally outside the first rod body 10 and the third rod body 12 respectively through the sliding sleeve 14, so that the third rod body 12 slides along the first rod body 10 and gradually approaches The second rod 11 and the fourth rod 13 gradually approach the first rod 10 along the third rod 12 and the second rod 11, so that the distance between the first rod 10 and the third rod 12, and the distance between the second rod 11 and the fourth rod 13 gradually decreases, so as to ensure that the first rod 10, the second rod 11, the third rod 12 and the fourth rod 13 can reinforce and lock the outer side of the template. Specifically, the third rod 12 and the fourth rod 13 are put into sleeves. When the third rod 12 and the fourth rod 13 are close to and fit the outer side of the template, the first pull rod 23 and the second pull rod 23 are released. The pull rod 27 rotates the rotating rod 24 at this time, so that the rotating rod 24 drives the fixed gear 20 to mesh and move on the rack 100, so that the rotating rod 24 drives the third rod body 12 and the fourth rod body 13 to move along the first rod body 10 and the third rod body 12 respectively through the sliding sleeve 14. When the fixed gear 20 rotates, the locking spring 22 squeezes the locking rod 21 into the slots 201 at different positions to prevent the fixed gear 20 from rotating in the opposite direction. When the rotating rod 24 drives the fixed gear 20 to rotate, the return spring 26 squeezes the lever 25 to move to the outside of the rotating rod 24. The lever 25 is moved so that the lever 25 can be clamped in the slot 201 on the side of the fixed gear 20 to drive the fixed gear 20 to rotate. When the rotating rod 24 rotates in the opposite direction, the inclined surface of the lever 25 can make the lever 25 squeeze the return spring 26 to make the lever 25 move toward the inner side of the rotating rod 24. In this way, the lever 25 and the plurality of slots 201 are constantly clamped in and out without driving the fixed gear 20 to rotate in the opposite direction. The locking rod 21 and the inclined surfaces of the lever 25 can ensure that the fixed gear 20 rotates in the direction close to the template without moving in the opposite direction.After one end of the third rod body 12 and the fourth rod body 13 are adjusted by the sliding sleeve 14, the squeezing rod 33 is rotated by the handle 34, so that the squeezing rod 33 drives the two squeezing blocks 330 to rotate simultaneously, so that the distance between the edge of the squeezing block 330 and the central axis of the squeezing rod 33 gradually increases, and the two abutting rods 31 are squeezed at the same time, so that the two abutting rods 31 squeeze the side edges of the second rod body 11 and the fourth rod body 13 respectively so as to lock and fix the second rod body 11 and the fourth rod body 13 in the slider 30 at the same time, and when the abutting rod 31 squeezes and locks the side edges of the second rod body 11 and the fourth rod body 13, the rough surfaces of the side edges of the second rod body 11 and the fourth rod body 13 avoid or even reduce the sliding between the two and the slider 30, and the squeezing rod 33 can drive the ratchet 35 to rotate while rotating, and at this time the pawl 37 can disengage from the teeth of the ratchet 35 outside the ratchet 35 When the second rod 11 and the fourth rod 13 slide sideways, and the second rod 11 and the fourth rod 13 are squeezed and locked by the push rod 31 in the slider 30, the pawl 37 can lock the squeezing rod 33 through the ratchet wheel 35, so that the second rod 11 and the fourth rod 13 are locked and fixed in the slider 30, avoiding the second rod 11 and the fourth rod 13 from sliding in the slider 30 and causing the template to loosen; and when removing, when the paddle plate 39 is toggled in the direction away from the fixed gear 20, the paddle plate 39 drives the pawl 37 to squeeze the clamping spring 38 to release the lock of the ratchet wheel 35, so that the handle 34 drives the squeezing rod 33 to rotate in the opposite direction and reset, so that the squeezing rod 33 gradually reduces the squeezing force on the push rod 31, so that the connecting spring 32 drives the push rod 31 to reset, so that the push rod 31 releases the lock of the second rod 11 and the fourth rod 13, and the fourth rod 13 is easily removed from the second rod 11;

[0067] After the first reinforcement component 1 reinforces the outer side of the template, the second reinforcement component 1, the third reinforcement component 1, and so on are installed in sequence according to the size of the template and actual needs, so that multiple reinforcement components 1 can reinforce the outer side of the template at different positions. After the multiple reinforcement components 1 are installed, the first clamp 400 provided on the support rod 40 and the second clamp 420 provided on the sliding rod 42 are connected through the concave-convex fit between the groove 401 and the protrusion 421 and the locking bolt 41, so that the support component 4 supports and locks the adjacent first rod body 10, second rod body 11, third rod body 12 or fourth rod body 13 at different positions, and in order to adapt to and fix the adjacent first rod body 10, second rod body 11, third rod body 12 or fourth rod body 13 at different positions, by pressing the adjustment rod 43, the adjustment rod 43 squeezes the adjustment spring 44 to move into the sliding rod 42, thereby adjusting the sliding rod 42 to slide in the support rod 40, and the space between the support rod 40 and the sliding rod 42 After the total length adjustment is completed, the adjustment spring 44 can squeeze the adjustment rod 43 to move outward along the sliding rod 42, so that the adjustment rod 43 is stuck in the clamping holes at different positions, so as to adjust the total length between the support rod 40 and the sliding rod 42 to adapt to the adjacent first rod body 10, second rod body 11, third rod body 12 or fourth rod body 13 at different positions and fix them, so as to avoid the template from shaking or even falling apart during use; in addition, the first clamp 400 and the second clamp 420 are installed through the concave-convex matching between the groove 401 and the protrusion 421, so as to ensure that the first clamp 400 of the last installed support component 4 is on the outside of the second clamp 420 of the previously installed support component 4, that is, the previously installed support component 4 is on the inside of the last installed support component 4, so that when installing and disassembling the reinforcement component 1 and the support component 4, they must be disassembled and assembled in sequence, that is, they must be disassembled one by one in sequence when disassembling, so as to ensure safety;

[0068] In order to adapt to templates of different sizes to improve the applicability of the reinforcement device, the extension rod 50 is installed at the free ends of the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 through the cooperation between the threaded column 501 and the threaded hole, and the slide grooves at the free ends of the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 are aligned and connected with the slide grooves provided on the extension rod 50. At this time, the threaded rod 51 is rotated so that the threaded rod 51 drives the clamping block 52 to slide along the slide groove of the extension rod 50 to the slide grooves of the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13, and the pin column is clamped into the clamping hole of the clamping block 52. At this time, the clamping block 52 is between the extension rod 50 and the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13, so that the clamping block 52 can clamp and limit the installed extension rod 50 to prevent the extension rod 50 from rotating and moving after installation. In this way, the first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 are all extended by the extension rod 50 connected thereto, thereby adapting to templates of different sizes and improving the applicability of the reinforcement device; the extension rod 50 having the same shape as the connected first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13 can avoid the situation that the locking assembly 2, the fixing assembly 3 and the supporting assembly 4 are difficult to fully reinforce the template during use due to the difference in shape between the extension rod 50 and the connected first rod body 10, the second rod body 11, the third rod body 12 and the fourth rod body 13.
