[0002] A sub-saw is a sawing device that is equipped with a sub-saw (small saw blade) and a mother saw (large saw blade). The sub-saw is mainly responsible for shallow cutting and marking, while the mother saw is mainly responsible for cutting. During the assembly of the sub-saw, the sub-saw is leveled with the mother saw as a reference, and the position of the sub-saw is adjusted to make it flush with the mother saw. However, the existing sub-saw adjustment is very complicated, troublesome and time-consuming. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the utility model is to provide a sub-saw leveling mechanism to solve the above technical problems.

[0004] The technical solution adopted by the utility model to solve the technical problem is as follows:

[0005] According to one aspect of the utility model, a sub-saw leveling mechanism is designed, including: a frame, a shell, a motor and a leveling bolt, the shell is arranged on the front side of the frame, the motor is installed on the shell, and brackets connected to the frame are respectively provided on the left side, the right side and the bottom of the shell, and the adjustment parts on the three brackets respectively extend into the frame through the avoidance holes on the shell, the rod parts of the three leveling bolts are movably matched with the three movable holes on the shell and correspondingly threadedly matched with the three threaded holes on the adjustment parts, and the leveling bolt is connected to a driving member which can drive the shell to move relative to the adjustment part when the leveling bolt is screwed.

[0006] By adopting the above technical scheme, when the leveling bolt on the left or right end of the shell is screwed, the left or right end of the shell can be driven to swing back and forth, and the forward and backward swinging of the left or right end of the shell is linked to the swinging of the motor, and the driving shaft of the motor is used to connect the saw blade, so that the swinging of one end of the saw blade can be adjusted, thereby realizing the adjustment of the straightness of the saw blade in the lateral direction; when the leveling bolts on the left and right sides are screwed at the same time, the driving motor can be driven to move forward and backward as a whole, thereby realizing the adjustment of the forward and backward movement of the saw blade as a whole; when the leveling bolt at the lower end of the shell is screwed, the lower end of the shell can be driven to swing back and forth, and the forward and backward swinging of the lower end of the shell is linked to the swinging of the motor, and the driving shaft of the motor is used to connect the saw blade, so that the swinging of the lower end of the saw blade can be adjusted, thereby realizing the adjustment of the verticality of the saw blade in the vertical direction. Therefore, the three leveling bolts can be used to realize the all-round adjustment and leveling of the motor and the saw blade, and the adjustment is simple and fast.

[0007] In order to better solve the above technical defects, the utility model also has a better technical solution:

[0008] In some embodiments, the driving member is a spring, which is sleeved on the rod body, and has one end abutting against the housing and the other end abutting against the adjusting portion.

[0009] In some embodiments, the driving member is an open retaining spring, and the open retaining spring is clamped to the rod body to limit the axial movement of the leveling bolt relative to the housing.

Thus, the lead screw can be driven to rotate by rotating the screwing portion, and the rotation of the lead screw drives the adjusting nut to rise and fall. The raising and lowering of the adjusting nut can be linked to the raising and lowering of the motor. The driving shaft of the motor is used to connect the saw blade, thereby realizing the height adjustment of the saw blade.

[0011] In some embodiments, a locking plate fixed to the screw is provided at the bottom of the housing, a ball plunger is fixed to the locking plate, and the ball head of the ball plunger cooperates with a plurality of locking parts arranged on the circumference of the housing to limit the rotation of the locking plate. Thus, when a tool is used to drive the screw to rotate, the locking plate can be linked to rotate, and when the screw stops rotating, the ball head of the ball plunger on the locking plate cooperates with the locking part on the housing to limit the rotation of the locking plate, thereby limiting the rotation of the screw and preventing the height of the saw blade from changing due to the rotation of the screw caused by the vibration caused by the saw blade during sawing.

[0012] In some embodiments, the adjusting nut is fixedly connected to a connecting member, and the connecting member is fixedly connected to the front end cover.

[0013] In some embodiments, a limit plate is provided on the front side of the leveling bolt to limit its forward movement distance, and the limit plate is connected to the housing via a connecting bolt, so that when the leveling bolt is screwed, the leveling bolt can be prevented from being separated from the adjustment part.
