Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Referring to fig. 1-3, a convenient-to-operate's digger, including stock 1, stock 1 lower extreme is equipped with the screw thread, stock 1 downside can be dismantled and be equipped with shovel head 2, stock 1 passes through screw thread connection shovel head 2, stock 1 periphery is equipped with supporting component, supporting component includes axis of rotation 3, stock 1 one side is equipped with the through-hole, axis of rotation 3 rotatable coupling stock 1, axis of rotation 3 suits with the through-hole, the both ends that axis of rotation 3 kept away from are rotatable to be equipped with L type frame 4, L type frame 4 one side is equipped with reinforcing bar 5, stock 1 one side is equipped with backup pad 6, backup pad 6 fixed connection makes it have laborsaving function between two L type frames 4, also can accomplish the operation of digger to the weaker student of strength, during specific use: for students with larger strength, the supporting component can be removed, for students with weaker strength, the supporting component can enable the operation of the soil digger to be more labor-saving, the rotating shaft 3 is adjusted, after a proper through hole is selected, the students hold the long rod 1 in a handheld mode, the shovel head 2 is inserted into the soil to be dug, the long rod 1 is pressed backwards, after the L-shaped frame 4 is contacted with the ground, a lever mechanism is formed, and the students only need to press the long rod 1 forcefully to be far away from the shovel head end, so that the soil can be dug.

The telescopic rod 1 upper end is equipped with extension subassembly, but extension subassembly includes telescopic rod 7, but telescopic rod 7 sliding connection is in telescopic rod 1 periphery, and telescopic rod 7 lower extreme is fixed to be equipped with screw shrinkage sleeve 8, and screw shrinkage sleeve 8 periphery can be dismantled and be equipped with lock sleeve 9, makes it have the function of adjustable length, to the student of different heights, different age bracket, can adjust the excavator to suitable length according to self needs, provides better effect for the teaching, when concrete implementation: before the telescopic rod is used, the locking sleeve 9 is unscrewed, so that the telescopic rod 7 slides on the periphery of the long rod 1, and after the telescopic rod is adjusted to a proper position, the locking sleeve 9 is screwed again, so that the thread shrinkage sleeve 8 can be tightly pressed on the periphery of the long rod 1.

The upper side of the shovel head 2 is fixedly provided with a pedal 10, and the long rod 1, the shovel head 2 and the locking sleeve 9 are subjected to chamfering treatment. The pedal 10 can improve the soil digging efficiency and increase the digging depth of the shovel head, so that the excavator can dig more soil at one time, and the chamfering effect is to effectively avoid the damage of students in the use process.

The working principle and the using method of the utility model are as follows: before the excavator is used, whether a supporting component is installed or not is selected according to the needs of students, the length of the excavator is adjusted according to the self conditions of the students, firstly, the locking sleeve 9 is unscrewed, the telescopic rod 7 slides on the periphery of the long rod 1 and is adjusted to a proper position, then the locking sleeve 9 is screwed, the thread shrinkage sleeve 8 can be tightly pressed on the periphery of the long rod 1, when the excavator is used, the shovel head 2 is placed on the surface of the ground to be excavated, the foot pedal 10 is stepped down by feet, the shovel head 2 is inserted into the ground, for students without the supporting component, one hand stretches the shovel head end close to the long rod 1, and the other hand presses the shovel head end far away from the long rod 1, so that the excavator can be used; for students using the supporting component, the long rod 1 can be pressed down backwards by two hands, after the L-shaped frame 4 contacts the ground, a lever mechanism is formed, and under the action of the lever principle, the students can scoop up soil by pressing down the long rod 1 away from the shovel head end forcefully, so that the shoveling operation is completed.

It should be noted that:

the shovel head 2, the thread shrinkage sleeve 8 and the locking sleeve 9 provided by the application are all of the prior art, and specific functions and usage thereof are not repeated.
