Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The embodiment of the utility model provides a manual cutting machine, as shown in fig. 1-4, the manual cutting machine comprises a base 1, two mounting blocks 2 are oppositely arranged at the top of the base 1, mounting grooves 21 are formed in opposite sides of the two mounting blocks 2, bolts 3 are connected to the tops and bottoms of the two mounting blocks 2 in a threaded mode, bearings 4 are arranged in the mounting grooves 21 of the two mounting blocks 2, the two bearings 4 are respectively sleeved at two ends of a rotating shaft 5, the side wall of the rotating shaft 5 is connected with the lower end of a swinging frame 6, a motor 7 is arranged at the upper end of the swinging frame 6, a cutting knife 8 is arranged on an output shaft of the motor 7, in use, the cutting knife 8 can be driven to rotate through the swinging frame 6, meanwhile, materials to be cut can be cut through the motor 7, therefore, the cutting knife 8 can deviate from a vertical state after the cutting machine is used for a period of time, the heights of the bearings 4 in the corresponding mounting blocks 2 can be adjusted through adjusting the bolts 3 in the tops and bottoms of any one mounting block 2, the heights of the bearings 4 in the corresponding mounting blocks 2 can be adjusted, so that the cutting knife 8 can deviate from the vertical state when the cutting knife 8 is convenient to cut in the vertical state after adjustment.
It should be noted that, the bottom of the base 1 is provided with a cavity, and the head of the bolt 3 at the bottom of the mounting block 2 is provided inside the cavity, so that the bolt 3 at the bottom of the mounting block 2 can be conveniently adjusted.
In this embodiment, nut 9 is all installed to installation piece 2 top and bottom, and bolt 3 threaded connection is inside nut 9, can realize at installation piece 2 top and bottom equal threaded connection bolt 3.
In order to facilitate the user to swing the swing frame 6, the handle bar 10 is mounted on the swing frame 6, and the user can hold the handle bar 10 by hand when swinging the swing frame 6, thereby facilitating the user to swing the swing frame 6.
In this embodiment, the mounting groove 21 inside of two installation pieces 2 all is equipped with the lag 11 with mounting groove 21 assorted, two bearings 4 are installed respectively inside two lag 11, lag 11 can be at the inside stable reciprocates of mounting groove 21, thereby can conveniently adjust the height of bearing 4, lag 11 can be when adjusting and fixing the height of bearing 4 simultaneously, avoid bolt 3 and bearing 4 direct contact, in order to avoid bolt 3 to crush bearing 4, the inside mounting hole that is equipped with of lag 11 simultaneously, the opening that the one end of mounting hole diameter is less is close to mounting groove 21, bearing 4 installs inside the one end that the mounting hole diameter is great, can avoid the dust to enter into inside bearing 4, improve the life of bearing.
It should be noted that, the heads of the bolts 3 at the top and the bottom of the mounting block 2 are respectively arranged outside the mounting groove 21, one ends of the bolts 3 at the top and the bottom of the mounting block 2, which are far away from the heads, are respectively arranged inside the mounting groove 21, when the height of the bearing 4 is adjusted, one of the bolts 3 is loosened, the other bolt 3 is adjusted to enable the other end of the other bolt 3, which is far away from the heads, to be abutted against the protecting sleeve 11, the height of the protecting sleeve 11 is adjusted, so that the height of the bearing 4 can be adjusted, and after the adjustment is completed, the two bolts 3 are adjusted to enable the ends of the two bolts 3, which are far away from the heads, to be respectively abutted against and fastened at the top and the bottom of the protecting sleeve 11, so that the height of the protecting sleeve 11 can be fixed, and the height of the bearing 4 can be fixed.
In this embodiment, connect through spring 12 between base 1 and the swing frame 6, the spring 12 can make cutting knife 8 restore to the original state after cutting knife 8 finishes the material to can make things convenient for cutting knife 8 to cut the material, more specifically, swing frame 6 lower extreme both ends all are equipped with installation cover 61, and two installation covers 61 are coaxial arrangement respectively on pivot 5, and spring 12 is the torsional spring and overlaps and establish the position that is located between the installation cover 61 both ends at pivot 5, simple structure, reasonable in design.
The material to be cut is placed at the bottom of the base 1 in use, a user holds the handle rod 10 by hand to swing the swing frame 6, the swing frame 6 can drive the cutting knife 8 to move up and down, meanwhile, the motor 7 can drive the cutting knife 8 to rotate, the material to be cut is cut, the handle rod 10 is loosened after the cutting is finished, the cutting knife 8 can be restored to the original state through the spring 12 so as to facilitate the next cutting, after the cutting machine is used for a period of time, the cutting knife 8 deviates from the vertical state, therefore, the cutting effect on the material can be influenced, the height of the bearing 4 in the corresponding mounting block 2 can be adjusted by adjusting the bolts 3 at the top and the bottom of any one of the mounting blocks 2, so that the cutting knife 8 deflects, and after the adjustment is finished, the bearing 4 in the corresponding mounting block 2 can be fixed by the bolts 3 at the top and the bottom of the mounting block 2, and therefore, the cutting knife 8 can be conveniently adjusted to the vertical state when the cutting knife 8 deviates from the vertical state.
The above-described embodiments of the present utility model do not limit the scope of the present utility model. Any other corresponding changes and modifications made in accordance with the technical idea of the present utility model shall be included in the scope of the claims of the present utility model.
