[0042] In the embodiments of the present disclosure, as shown in Figure 1 、 Figure 2 、 Figure 3 As shown, the swinging of the handle 301 is meshed with the driving frame 303 through the gear 302, so as to accurately control the horizontal movement of the spade 402, the operator can accurately control the contact position and degree of the blade edge of the spade 402 and the soil layer by adjusting the swinging angle and amplitude of the handle 301 according to the excavation requirement, for example, when the soil layer near the steam pipeline needs to be slightly loosened, the operator only needs to swing the handle 301 with small amplitude, the gear 302 drives the driving frame 303 to move in a small range, and the spade 402 can realize accurate horizontal displacement, so as to avoid damage to the steam pipeline caused by the traditional spade 402 which is difficult to control the force and position by manual swinging;

[0043] In the embodiments of the present disclosure, as shown in Figure 4 、 Figure 5As shown, during the downward digging process, when the handle 301 is subjected to downward pressure, the spring installed on the positioning rod 201 is compressed to generate a buffering force. The operator can clearly feel the spring buffering feedback through the hands, thereby adjusting the force in real time. For example, when the spring is compressed to a certain extent and the operator feels that the resistance increases, it means that the spade 402 has cut into the appropriate depth. At this time, the force can be appropriately reduced to avoid excessive force damaging the steam pipeline. This force control method through spring feedback enables the operator to more accurately control the digging force of the spade 402, ensuring the safety and accuracy of the excavation work.

[0044] In Example Two, on the basis of Example One, referring to Figures 1 to 8 As shown, when detecting the soil layer around the steam pipeline, the worker directly applies a pressing force to the handle 301 to move the spade 402 vertically downward to detect the soil layer around the steam pipeline, thereby increasing the function of the excavation structure 4 for detecting the soil layer.

[0045] The working principle of this embodiment is as follows:

[0046] Preparation steps before assembling the excavation device,

[0047] The worker checks all parts to ensure that the support frame 1 has no deformation or cracks, the internal threads of the bottom threaded holes are clear and undamaged, so as to facilitate the subsequent installation and adjustment of the bolts, checks the driving mechanism 3, and ensures that the handle 301 feels comfortable and has no looseness or cracks. The screws connecting the gear 302 are tightened, the gear 302 has complete and undamaged teeth without wear, the rotating block is smooth and undamaged, the rectangular sliding hole of the driving frame 303 is regular, and the meshing teeth are clear and undamaged, so as to ensure that the gear 302 can smoothly control the lateral movement of the driving frame 303 when rotating.

[0048] The worker installs the positioning frame 2 inside the support frame 1, so that the positioning rod 201 of the positioning frame 2 passes through the sliding hole above the support frame 1, ensuring that the two positioning rods 201 are accurately matched to achieve the circumferential and lateral positioning of the positioning frame 2. The spring is installed with the support spring, so that the positioning frame 2 can automatically reset after being forced to move. The smoothness of the upward and downward movement of the positioning frame 2 is checked. If there is a jam, the positioning rod 201 or the sliding hole is adjusted.

[0049] The worker installs the gear 302 at the bottom of the positioning frame 2, the rotating block passes through the rotating hole, and the gear 302 can rotate flexibly in place inside the rotating hole. The handle 301 is inserted into the guide hole, the handle 301 is swung to test whether the gear 302 rotates flexibly, one side of the driving frame 303 passes through the rectangular sliding hole of the positioning frame 2, and the driving frame 303 is circumferentially positioned accurately. The meshing teeth of the driving frame 303 and the gear 302 are engaged.

[0050] Select the appropriate material hand rod 401, inserted into the vertical mounting hole of the drive frame 303, tighten the locking bolt, make the hand rod 401 and drive frame 303 stable connection, the butt joint rod 403 of the spade 402 is inserted into the butt joint groove at the bottom of the hand rod 401, and the locking block is clamped into the locking groove of the butt joint rod 403 under the action of the supporting spring, the quick assembly and locking of the spade 402 and the hand rod 401 are completed;

[0051] Before the excavation operation is performed, the support frame 1 is placed at the predetermined position according to the working site condition, if it is necessary to fine-tune the excavation angle, the small range angle adjustment of the device can be realized by rotating the adjusting bolt (such as Figure 4 shown) at the bottom of the support frame 1, so as to adapt to different excavation requirements, for example, when fine excavation is needed at a specific position close to the steam pipeline, the spade 402 can be more accurately aligned with the excavation position through the adjusting bolt;

[0052] When the excavation direction needs to be converted by a larger angle, since the overall weight of the device is light (the materials of various components are light and firm, such as Figure 7 shown), the operator can easily rotate the device as a whole to the appropriate position (such as Figure 8 shown), and in the process of excavation, the operator can also change the earth penetration angle of the spade 402 by adjusting the holding position and swing angle of the handle 301. For example, when oblique excavation is needed, the handle 301 can be held obliquely to one side and the swing angle is appropriately adjusted, so that the spade 402 cuts into the soil layer at an appropriate angle, increasing the flexibility of the excavation angle and meeting the needs of different excavation scenes;

[0053] The worker places the support frame 1 at the predetermined position according to the working site condition, the operator holds the handle 301 and stands at the appropriate position, faces the area to be excavated, aligns the spade 402 with the soil layer above the steam pipeline pit detection position, slowly swings the handle 301, drives the spade 402 to move horizontally through the meshing transmission of the gear 302 and the drive frame 303, makes the blade of the spade 402 fully contact with the soil layer, loosens the soil layer by horizontal movement, when the spade 402 is in the appropriate position, gradually applies downward pressure to the handle 301, and at the same time cooperates with the supporting spring buffer to make the spade 402 vertically cut into the soil layer, excavates a certain amount of soil, controls the pressure of the handle 301 to avoid excessive force of the spade 402 damaging the steam pipeline;

[0054] After the soil is excavated to a certain depth or a digging action is completed, the pressure of the handle 301 is released, the positioning frame 2 drives the spade 402 to reset upward under the action of the supporting spring, the excavated soil is cleaned aside, the above steps are repeated to continuously excavate the steam pipeline pit detection position flexibly, and then the existing detection instrument is used to detect the steam pipeline pit;

[0055] If the shovel 402 needs to be replaced, the locking frame 404 is pulled outward to unlock the docking rod 403, the old shovel 402 is removed, and the desired type of shovel 402 is replaced and relocked according to the steps.
