[0022] like Figures 1-5 As shown, an angle-adjustable locking structure and operating lever include a mounting base 1 on which an operating lever 2 arranged in a circular array is rotatably mounted. A drive base 3 is also rotatably mounted coaxially within the mounting base 1. The drive base 3 is driven to rotate so as to drive the operating lever 2 to rotate relative to the axis of the mounting base 1 and move closer together so that the angle of the operating lever 2 is adjustable.

[0023] Specifically, as shown in Figure 1 the mounting seat 1, and a plurality of operating rods 2 are arranged in a circular array on the mounting seat 1 and are rotationally arranged on the mounting seat 1. The driving seat 3 can be manually driven to rotate, and the driving seat 3 drives the operating rods 2 to rotate and close to the axis direction of the mounting seat 1, thereby realizing the angle adjustment of the operating rods 2 relative to the mounting seat 1. The operating rods 2 can be rotated and closed to the axis direction of the mounting seat 1 to increase the length of the arm required to be stretched by the user when operating the bench drill, thereby facilitating the use of operators with different arm spans and heights and reducing safety hazards.

[0024] In the above technical solution, the driving seat 3 arranged on the mounting seat 1 can be manually driven to rotate, and the driving seat 3 drives the operating rods 2 to rotate and close to the axis direction of the mounting seat 1, thereby realizing the angle adjustment of the operating rods 2 relative to the mounting seat 1. The operating rods 2 can be rotated and closed to the axis direction of the mounting seat 1 to increase the length of the arm required to be stretched by the user when operating the bench drill, thereby facilitating the use of operators with different arm spans and heights and reducing safety hazards.

[0025] As a further provided embodiment of the utility model, a driving gear 6 and a transmission gear 7 are rotationally arranged in the mounting seat 1. The driving gear 6 is provided with a second bevel gear portion 61. The operating rod 2 is provided with a first rotating portion 22. The first rotating portion 22 is provided with a first bevel gear portion 221. The first rotating portion 22 is rotationally arranged in a mounting groove 12 formed in the mounting seat 1. The driving seat 3 is provided with a ring gear portion 31. The ring gear portion 31 is coupled with the transmission gear 7. The transmission gear 7 is coupled with the driving gear 6. The first bevel gear portion 221 of the driving gear 6 is coupled with the first bevel gear portion 221 of the first rotating portion 22.

[0026] Specifically, as shown in Figure 4 the driving gear 6 and the transmission gear 7 are rotationally arranged. The driving seat 3 can be manually rotated. The ring gear portion 31 of the driving seat 3 rotates to drive the transmission gear 7 to rotate. The transmission gear 7 rotates to drive the first bevel gear portion 221 of the driving gear 6 to rotate axially. At this time, the operating rod 2 is driven by the driving gear 6 to rotate relative to the axis of the mounting seat 1. In turn, the driving seat 3 drives the rotation of the operating rod 2 by using the driving gear 6, the transmission gear 7 and the ring gear portion 31, thereby improving the stability of the driving rotation of the operating rod 2 and facilitating actual operation and use.

[0027] As the further provided embodiment of the utility model further includes locking lever 4, drive base 3 is provided with the holding portion 32 that stretches outside mounting base 1, the holding portion 32 is provided with the threaded mounting hole 33 in circumferential array, locking lever 4 is screwed in threaded mounting hole 33 and end portion is in contact with mounting base 1 to lock drive base 3.

[0028] Specifically, as shown in Figure 1 The holding portion 32 of the drive base 3 stretches outside the mounting base 1, and the holding portion 32 can be manually rotated to drive the drive base 3 to rotate, so that the drive base 3 rotates to drive the operating lever 2 to rotate and swing relative to the axis direction of the mounting base 1 to approach or move away, thereby achieving angle adjustment of the operating lever 2. When the angle adjustment of the operating lever 2 is completed, the drive base 3 can be locked relative to the mounting base 1 by screwing the locking lever 4 into the threaded mounting hole 33 and making the end of the locking lever 4 contact the mounting base 1, thereby locking and fixing the angle position of the operating lever 2, avoiding accidental movement of the operating lever 2 during use, and preventing the problem of slipping off the hand, thereby improving the safety during use.

The drive base 3 is driven to rotate so that the pushing portion 311 rotates and extrudes the butter in the storage cavity 13 to enter the mounting groove 12 through the communication groove 14.

[0030] Specifically, as shown in Figure 2 The storage cavity 13 and the communication groove 14 are formed in the mounting base 1, the communication groove 14 connects the storage cavity 13 and the mounting groove 12, and the pushing portion 311 of the drive base 3 extends into the storage cavity 13. The butter can be injected into the storage cavity 13 through the injection hole 34. When the angle of the operating lever 2 is adjusted, the drive base 3 is driven to rotate so that the pushing portion 311 rotates and extrudes the butter in the storage cavity 13 to enter the mounting groove 12 through the communication groove 14, thereby extruding the debris or dust in the mounting groove 12 during the operation of the drill, avoiding the problem of rotation jamming of the operating lever 2 caused by the debris or dust in the mounting groove 12, and improving the use stability of the operating lever 2. In addition, the butter enters the storage cavity 13 and the mounting groove 12 to improve the rotation of the ring tooth portion 31 and the operating lever 2, reduce the rotation friction, facilitate actual use, and when the drill is used for tapping or boring operation, if the working temperature of the drill bit is too high, the drive base 3 can also be rotated to extrude the butter to overflow from the mounting groove 12, and the butter can be applied to the drill bit to reduce the working temperature of the drill bit, and also has the effect of cooling and lubricating in subsequent operation.

[0031] Further, a blocking block 5 for blocking the injection hole 34 is further included, which is used to avoid the butter flowing out from the injection hole 34.

[0032] As further provided by the utility model, the end of the operating rod 2 is provided with a ball handle 21, and a threaded matching hole 23 is further formed on the operating rod 2, and the locking rod 4 is screwed on the threaded matching hole 23 to form an L shape with the ball handle 21.

[0033] Specifically, since the driving seat 3 is provided with multiple locking rods 4 to lock the driving seat 3, when fine drilling work is needed for the workpiece, the bench drill handle has a small rotation range, and the pressing force required by the operator is more fine, one locking rod 4 can be removed from the driving seat 3 and installed on the threaded matching hole 23 of the operating rod 2, so that the locking rod 4 and the ball handle 21 of the operating rod 2 form an L-shaped holding bracket, thereby being more convenient for the operator to hold and exert force, and avoiding the problem of slipping.

[0034] As further provided by the utility model, the driving seat 3 is provided with a second rotating part 35, and the second rotating part 35 is rotatably arranged in the rotating groove 15 formed on the mounting seat 1.

[0035] Specifically, the driving seat 3 is provided with a second rotating part 35, and the second rotating part 35 is rotatably arranged in the rotating groove 15 formed on the mounting seat 1, so as to improve the rotating stability of the driving seat 3 by using the second rotating part 35 and the rotating groove 15.

[0036] The above only describes some exemplary embodiments of the utility model by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the utility model for ordinary skilled in the art.
